This book was released on 2005 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Cont.) To interpret the fluorescence measurements of the mechanical properties of double-stranded DNA, a worm-like chain model is used as a first-principle model to study double-stranded DNA under hydrodynamic flows. The second part of the thesis concentrates on nonperturbative vibrational energy relaxation (VER) effects of vibrational line shapes. In general, nonperturbative and non-Markovian VER effects are demonstrated more strongly on nonlinear vibrational line shapes than on linear absorption.

Book excerpt: In this thesis, several problems regarding dynamics and spectra in condensed phases are theoretically analyzed via analytical models. The thesis consists of four main topics. First, a theoretical description of single molecule spectroscopy is presented in order to study time-dependent fluctuations of single molecule spectra in a dynamic environment. In particular, the photon counting statistics is investigated for a single molecule undergoing a generic type of spectral diffusion process. An exact analytical solution is found for this case, and various physical limits are analyzed. Second, motivated by recent experimental observations of anomalous spectral fluctuations in quantum dot systems, both the lineshape phenomenon and the photon counting statistics are explored when spectral fluctuations are characterized by power-law statistics, for which there is no finite timescale. Unique features of the power-law statistics are demonstrated in spectral properties of those systems. Third, a spectral analysis method is developed for the non-adiabatic electron transfer reactions, which allows a unified treatment of diverse kinetic regimes in the electron transfer process. The method is applied to electron transfer reactions in mixed-valence systems in order to explore the possibility of electronic coherence. Finally, effects of the nonequilibrium bath relaxation on the excitation energy transfer process are investigated by generalizing the Forster-Dexter theory of excitation energy transfer to the case of the nonstationary bath relaxation.

Book Synopsis Spectroscopy of Condensed Media by : C.H. Wang
Download or read book Spectroscopy of Condensed Media written by C.H. Wang and published by Elsevier. This book was released on 2012-12-02 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectroscopy of Condensed Media: Dynamics of Molecular Interactions discusses the use of molecular spectroscopy (including nuclear magnetic resonance [NMR] and nonlinear optical spectroscopy) in dynamic processes in condensed molecular systems. The book reviews relationship between transition probability and the time-correlation function of an isotropic electric dipole system, linear-response theory, and light scattering resulting from the translational motion of molecules in fluids. The text describes molecular rotation, theories of angular momentum, nuclear magnetic resonance, and spontaneous and coherent Raman effects. Closely related with the Raman and Brillouin scattering are vibrational dephasing, relaxation processes, and dynamics of phase transition solids. The book highlights the advantages of using NMR and also explains the basic concepts, such as local field, spin temperature, and effective Hamiltonians, that are employed in interpreting NMR experiments. The investigator can use nonlinear optical spectroscopy to study condensed matter. The text also cites two methods in which the investigator can control the time-dependent average Hamiltonian by (1) manipulating the intensity, timing, phase of the pulses, or (2) by sample spinning. The book is intended for advanced graduate students in physical chemistry that will equally benefit both investigators and scientists involved in physics research.

Book Synopsis Revealing the Structure and Dynamics of Small-molecule Solutions and Proteins Using Theoretical Vibrational Spectroscopy by :
Download or read book Revealing the Structure and Dynamics of Small-molecule Solutions and Proteins Using Theoretical Vibrational Spectroscopy written by and published by . This book was released on 2014 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the sensitivity of vibrational chromophores to their local environments, linear and ultrafast vibrational spectroscopy have proven to be very useful techniques for studying the structure and dynamics of condensed phases. Because spectroscopic techniques encode information related to the time-dependent configuration of an entire system into spectra resolved over at most a few dimensions, however, it is very difficult to interpret vibrational line shapes in a detailed and unambiguous manner. One approach to surmounting this difficulty is to calculate vibrational line shapes from molecular dynamics (MD) simulations by employing vibrational response theory and spectroscopic maps. (The maps relate observables in classical MD simulations to quantum spectroscopic quantities.) Once validated by comparison of experimental and theoretical line shapes, MD simulations can be used as an unequivocal basis for the interpretation of vibrational spectra. Here, we employ this approach in order to gain insight into small-molecule solutions and proteins. After sketching the theoretical formalism underlying the calculations of vibrational spectra (Chapter 2), vibrational spectroscopic analysis of the urea/water (Chapter 3) and cyanide/water (Chapter 4) solutions is presented. Analysis of linear infrared (IR) line shapes provides information concerning the local solvation structure of these molecules, while analysis of two-dimensional IR and anisotropy decay yields insight into frequency and rotational dynamics. The remainder of this work concerns the vibrational spectroscopy of the amide I (mostly CO-stretch) band of proteins. After presenting additional theoretical formalism and maps for protein spectroscopy (Chapter 5), the maps are evaluated by examining IR spectra for a single conformation of an alpha-helical model peptide in the gas phase (Chapter 6). These methods are then applied to evaluate the 2D IR spectra of two important biological systems: polyglutamine (Chapter 7) and the potassium ion channel KcsA (Chapter 8). Notably, these studies employ isotope-labeling techniques to isolate the vibrational response of a subset of amide I modes in a non-perturbative fashion. Finally, extensions to the theory are presented to enable the computation of amide I vibrational sum-frequency generation spectra (Chapter 9), which are expected to be sensitive to the structures of interfacial proteins.

Book Synopsis Vibrational Spectroscopy of Solids by : Peter Miles Anson Sherwood
Download or read book Vibrational Spectroscopy of Solids written by Peter Miles Anson Sherwood and published by CUP Archive. This book was released on 1972-09-21 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 1972 monograph is devoted to the analysis and interpretation of the infrared and Raman spectra of solid compounds, frequently used for their identification and characterization. It was thought unsatisfactory to analyse such spectra by the theory applicable to gas-phase samples, though this was frequently done. Furthermore, the results obtained by far infrared and laser Raman spectrometers, which detect the movement of atoms and/or molecules as a whole, had no gas-phase analogy. A separate approach to solid state vibrational spectra was therefore proposed within this volume. Dr Sherwood describes the solid state physics of vibrational spectroscopy and extends it to the more complex structures of low symmetry. He assumes an understanding of the infrared and Raman spectra of gases.

Book Synopsis Theoretical Modeling of Vibrational Spectra in the Liquid Phase by : Martin Thomas
Download or read book Theoretical Modeling of Vibrational Spectra in the Liquid Phase written by Martin Thomas and published by Springer. This book was released on 2016-12-24 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis provides a comprehensive description of methods used to compute the vibrational spectra of liquid systems by molecular dynamics simulations. The author systematically introduces theoretical basics and discusses the implications of approximating the atomic nuclei as classical particles. The strengths of the methodology are demonstrated through several different examples. Of particular interest are ionic liquids, since their properties are governed by strong and diverse intermolecular interactions in the liquid state. As a novel contribution to the field, the author presents an alternative route toward infrared and Raman intensities on the basis of a Voronoi tessellation of the electron density. This technique is superior to existing approaches regarding the computational resources needed. Moreover, this book presents an innovative approach to obtaining the magnetic moments and vibrational circular dichroism spectra of liquids, and demonstrates its excellent agreement with experimental reference data.

Download or read book Theoretical Methods in Condensed Phase Chemistry written by S.D. Schwartz and published by Springer Science & Business Media. This book was released on 2002-05-31 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is meant to provide a window on the rapidly growing body of theoretical studies of condensed phase chemistry. A brief perusal of physical chemistry journals in the early to mid 1980’s will find a large number of theor- ical papers devoted to 3-body gas phase chemical reaction dynamics. The recent history of theoretical chemistry has seen an explosion of progress in the devel- ment of methods to study similar properties of systems with Avogadro’s number of particles. While the physical properties of condensed phase systems have long been principle targets of statistical mechanics, microscopic dynamic theories that start from detailed interaction potentials and build to first principles predictions of properties are now maturing at an extraordinary rate. The techniques in use range from classical studies of new Generalized Langevin Equations, semicl- sical studies for non-adiabatic chemical reactions in condensed phase, mixed quantum classical studies of biological systems, to fully quantum studies of m- els of condensed phase environments. These techniques have become sufficiently sophisticated, that theoretical prediction of behavior in actual condensed phase environments is now possible. and in some cases, theory is driving development in experiment. The authors and chapters in this book have been chosen to represent a wide variety in the current approaches to the theoretical chemistry of condensed phase systems. I have attempted a number of groupings of the chapters, but the - versity of the work always seems to frustrate entirely consistent grouping.

Download or read book Vibrational Spectroscopy of Molecular Liquids and Solids written by S. Bratos and published by Springer. This book was released on 1980-06-30 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has its or1g1n in a NATO Summer School organized from June 25 to July 7 1979, in Menton, France. The purpose of this School was a comparative study of the various aspects of vibra tional spectroscopy in molecular liquids and solids. This field has been rapidly expanding in the last decade; unfortunately, its development took place independently for liquids and for solids. In these circumstances, the comparison of the basic concepts and techniques used in these two branches of physics appeared as a necessity. The lectures given at the Menton Advanced Study Institute, as well as the exceptionally fruitful and lively discussions which followed them confirmed this point of view. The need of putting together these lectures, in the form of a monograph, clearly appeared during the ASI and the lecturers accepted to write down the material they presented at the Institute, improved thanks to the remarks of the participants. It is the result of this collective work which appears in the familiar Plenum Series.
