Book Synopsis Photodissociation Dynamics by : Reinhard Schinke
Download or read book Photodissociation Dynamics written by Reinhard Schinke and published by Cambridge University Press. This book was released on 1995-05-11 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photodissociation induced by the absorption of single photons permits the detailed study of molecular dynamics such as the breaking of bonds, internal energy transfer and radiationless transitions. The availability of powerful lasers operating over a wide frequency range has stimulated rapid development of new experimental techniques which make it possible to analyse photodissociation processes in unprecedented detail. This text elucidates the achievements in calculating photodissociation cross-sections and fragment state distributions from first principles, starting from multi-dimensional potential energy surfaces and the Schrödinger equation of nuclear motion. Following an extended introduction in which the various types of observables are outlined, the book summarises the basic theoretical tools, namely the time-independent and the time-dependent quantum mechanical approaches as well as the classical picture of photodissociation. The discussions of absorption spectra, diffuse vibrational structures, the vibrational and rotational state distributions of the photofragments form the core of the book. More specific topics such as the dissociation of vibrationally excited molecules, emission during dissociation, or nonadiabatic effects are also discussed. It will be of interest to graduate students and senior scientists working in molecular physics, spectroscopy, molecular collisions and molecular kinetics.

Book Synopsis Photodissociation Dynamics of Polyatomic Molecules by : Hequan Zhao
Download or read book Photodissociation Dynamics of Polyatomic Molecules written by Hequan Zhao and published by . This book was released on 1997 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the photodissociation of acetophenone (C6H5COCH3) at 193 nm, two major primary processes, C6H5COCH3+hv[right arrow]] C6H5CO + CH3 (process 1) and C6H5+COCH3 (process 2), are observed. Data analysis shows that excited C6H5CO and CH3CO thus formed further decompose, yielding secondary products C6H5+CO and CH3+CO, respectively. For 248 nm excitation, the C6H5CO-CH3 bond energy has been determined to be 80.2±3 kcal/mol.
Book Synopsis Multiple-Photon Excitation and Dissociation of Polyatomic Molecules by : Cyrus D. Cantrell
Download or read book Multiple-Photon Excitation and Dissociation of Polyatomic Molecules written by Cyrus D. Cantrell and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 1970s, researchers in Canada, the Soviet Union and the United States discovered that powerful infrared laser pulses are capable of dissociating mole cules such as SiF4 and SF6' This result, which was so unexpected that for some time the phenomenon of multiple-photon dissociation was not recognized in many cir cumstances in which we now know that it occurs, was first publicized at a time when the possibility of using lasers for the separation of isotopes had attracted much attention in the scientific community. From the mid-1970s to the early 1980s, hun dreds of experimental papers were published describing the multiple-photon absorp tion of C02 laser pulses in nearly every simple molecule with an absorption band in the 9 - 11 jJm region. Despite this impressive volume of experimental results, and despite the efforts of numerous theorists, there is no agreement among re searchers in the field on many fundamental aspects of the absorption of infrared laser light by polyatomic molecules. This book is devoted to reviells of the experimental and theoretical research that provides the foundations for our current understanding of molecular multiple photon exc itat i on, and to rev i ews of research that is pert i nent to the 1 aser sep aration of isotopes.

Book Synopsis Time-Resolved Photoionisation Studies of Polyatomic Molecules by : Martin Alex Bjørnholst
Download or read book Time-Resolved Photoionisation Studies of Polyatomic Molecules written by Martin Alex Bjørnholst and published by Springer Nature. This book was released on 2020-08-03 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores how structure impacts the dynamics of organic molecules in an extensive and impressive range of femtosecond time-resolved experiments that are combined with state-of-the-art theoretical approaches. It explores an area of molecular dynamics that remains largely uncharted and provides an extraordinary overview, along with novel insights into the concept of the dynamophore – the functional group of ultrafast science. Divided into four parts, this book outlines both experimental and computational studies on the VUV photoinduced dynamics of four cyclic ketones and one linear ketone, the ring-opening and dissociative dynamics of cyclopropane, and the potential ultrafast intersystem crossing in three methylated benzene derivatives. Model systems for the disulfide bond and the peptide bond, both of which are related to the structure of proteins, are also investigated. This highly informative and carefully presented book offers a wealth of scientific insights for all scholars with an interest in molecular dynamics.
Book Synopsis Dissociative Recombination of Molecular Ions by : Mats Larsson
Download or read book Dissociative Recombination of Molecular Ions written by Mats Larsson and published by Cambridge University Press. This book was released on 2012-09-13 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dissociative recombination (DR) of molecular ions with electrons is a complex, poorly understood molecular process. Its critical role as a neutralising agent in the Earth's upper atmosphere is now well established and its occurrence in many natural and laboratory-produced plasma has been a strong motivation for studying the event. In this book theoretical concepts, experimental methodology and applications are united, revealing the governing principles behind the gas-phase reaction. The book takes the reader through the intellectual challenges posed, describing in detail dissociation mechanisms, dynamics, diatomic and polyatomic ions and related processes, including dissociative excitation, ion pair formation and photodissociation. With the final chapter dedicated to applications in astrophysics, atmospheric science, plasma physics and fusion research, this is a focused, definitive guide to a fundamental molecular process. The book will appeal to academics within physics, physical chemistry and related sciences.

Book Synopsis Studies of Photoinduced Molecular Dynamics Using a Fast Imaging Sensor by : Craig S. Slater
Download or read book Studies of Photoinduced Molecular Dynamics Using a Fast Imaging Sensor written by Craig S. Slater and published by Springer. This book was released on 2015-10-15 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work presented in this thesis involves a number of sophisticated experiments highlighting novel applications of the Pixel Imaging Mass Spectrometry (PImMS) camera in the field of photoinduced molecular dynamics. This approach represents the union of a new enabling technology (a multiple memory register, CMOS-based pixel detector) with several modern chemical physics approaches and represents a significant leap forward in capabilities. Applications demonstrated include three-dimensional imaging of photofragment Newton spheres, simultaneous electron-ion detection using a single sensor, and ion-ion velocity correlation measurements that open the door to novel covariance imaging experiments. When combined with Coulomb explosion imaging, such an approach is demonstrated to allow the measurement of molecular structure and motion on a femtosecond timescale. This is illustrated through the controlled photoexcitation of torsional motion in biphenyl molecules and the subsequent real-time measurement of the torsional angle.
