Available in PDF, EPUB and Kindle. Book excerpt: This ASI was planned to make a major contribution to the teaching of the principles and methods used in liquid phase ~esearch and to encourage the setting up of collaborative projects, as advocated by the European Molecular Liquids Group (secretary: Dr J. Yarwood, University of Durham, U. K. ). During the past five years considerable progress has been made in studying molecular liquids. The undoubted advantages of international collaboration led to the formation of the European Molecular Liquids Group (EMLG) in July 1981. The activities of the EMLG were widely disseminated in a special session of the European Congress on Molecular Spectroscopy (EUCMOS) held in September 1981 (for details, see J. Mol. Structure, 80 (1982) 375 - 421). Following the success of this meeting, it was thought that the aims and objectives of the E~G would be best served by the organisation of a broader-based gathering designed to attract those interested in the study of the structure, dynamics and interactions in the liquid state. Thanks to the generous support by the Scientific Affairs Division of NATO, it was possible to hold a NATO ASI on Molecular Liquids at the Italian Centre of Stanford University, Florence, Italy during June-July 1983. This book is based on the lectures presented at that meeting. The contents of this volume cover the three broad areas of current liquid phase research: (a) Analytical theory.

Book Synopsis Multidimensional Time-Resolved Spectroscopy by : Tiago Buckup
Download or read book Multidimensional Time-Resolved Spectroscopy written by Tiago Buckup and published by Springer. This book was released on 2018-12-07 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.
Book Synopsis Solute Dynamics in Liquid Systems by : Christopher Rumble
Download or read book Solute Dynamics in Liquid Systems written by Christopher Rumble and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This work reports on explorations into the effect of the liquid environment on the dynamics and kinetics of a range solute processes. The first study (Chapter 3) explores the photoisomerization of the rotor probe 9-(2-carboxy-2-cyanovinyl)julolidine, or CCVJ. Rotor probes are a class of fluorophores that undergo photoinduced isomerization reactions resulting in non-radiative relaxation out of the excited state. Literature reports had suggested that CCVJ exhibited a flow effect, in which the emission intensity of CCVJ increases when the fluorophore solution is flowed at modest rates. Using steady-state and time-resolved fluorescence and 1H-NMR spectroscopy we show that the flow effect can be attributed to creation of a mixture of fluorescent and non-fluorescent CCVJ isomers by the excitation.The next study, Chapter 4, examines the the fluorescence of DNA G-quadruplex structures (GQSs), non-helical single-stranded DNA structures that exhibit quantum yields significantly higher than helical DNA or its constituent bases. By using a constant GQS core sequence we show that the addition of dangling nucleotides can modulate emission from the GQS whereas conventional quenchers do not. The emission can also be altered by changes in temperature and addition of crowding reagents such as poly(ethylene glycol). Using time-resolved emission spectroscopy we show that GQS emission can be approximately dissected into two emitting populations with distinct kinetics.Chapters 5 and 6 report on the effects of solvation on charge transfer reactions in conventionalmolecular solvents and ionic liquid/conventional solvent mixtures. In Chapter 5 the excited state intramolecular proton transfer reaction of 4-N,N-diethylamino-3-hydroxyflavone (DEAHF) is studied using sub-picosecond Kerr-gated emission spectroscopy in mixtures of acetonitrile and propylene carbonate. Previous studies of DEAHF tautomerization had shown that the proton transfer rate and equilibrium constant are highly dependent on both solvation dynamics and solvent polarity. Using acetonitrile/propylene carbonate mixtures, which have nearly identical polarity but have solvation times that vary over an order of magnitude, we were able to demonstrate that fast solvation dynamics introduces a barrier to the reaction and slows down the proton transfer rate. In Chapter 6 the intramolecular electron transfer reaction of 9-(4-biphenyl)-10-methylacridinium (BPAc+) is studied in mixtures of an ionic liquid and acetonitrile. Using KGE and picosecond time-correlated single photon counting measurements we show that the BPAc+ electron transfer rate is highly correlated with the mixture solvation time, consistent with rates observed in conventional solvents.Finally, Chapters 7 and 8 are an exploration of solute rotational dynamics in ionic liquids (ILs). Solute rotations in these unique solvents have been shown to be non-diffusive and poorly predicted by hydrodynamic theories of friction. We set out to explore the mechanisms of solute rotation in ILs using a combination of experimental methods and molecular dynamics (MD) simulations. In Chapter 7 the rotational dynamics of benzene and the IL cation 1- ethyl-3-methylimidizolium are studied using a combination of 2H longitudinal spin relaxation (T1) measurements and MD simulations. Using the simulations for guidance, we were able to interpret T1 measurements outside of the extreme narrowing limit. After the realism of the simulations was validated, they were then used to show that benzene exhibits markedly different dynamics for spinning about the C6 symmetry axis and tumbling (rotation of the C6 axis), and that large amplitude jump motions and orientational caging are prominent features of benzenes rotations in ILs. Chapter 8 extends the benzene work to examine the effect of molecular size and charge distribution on solute rotational dynamics in ILs. Combining fluorescence anisotropy and T1 relaxation measurements with MD simulations of a carefully chosen set of probe molecules we show that molecular charge has only a modest effect of friction experienced by a rotating solute, whereas an increase in molecular size results in a substantial increase in rotation times. After validation of the simulations, we showed that large amplitude jumps and orientational caging dynamics, similar to what was observed with benzene, are also present in these solutes.

Download or read book Dielectric and Related Molecular Processes written by Mansel Davies and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued.

This book was released on 2012-12-06 with total page 612 pages. Available in PDF, EPUB and Kindle. Book excerpt: Liquid-crystalline phases are now known to be formed by an ever growing range of quite diverse materials, these include those of low molecular weight as well as the novel liquid-crystalline polymers, such phases can also be induced by the addition of a solvent to amphiphilic systems leading to lyotropic liquid crystals. Irrespective of the structure of the constituent molecules these numerous liquid-cl)'Stailine phases are characterised by their long range orientational order. In addition certain phases exhibit elements of long range positional order. Our understanding, both experimental and theoretical, at the molecular level of the static behaviour of these fascinating and important materials is now well advanced. In contrast the influence of the long range order; both orientational and positional, on the molecular dynamics in liquid Cl)'Stais is less well understood. In an attempt to address this situation a NATO Advanced Study Institute devoted to liquid ctystal dynamics was held at n Ciocco, Barga, Italy in September 1989. This brought together experimentalists and theoreticians concerned with the various dynamical processes occurring in all liquid crystals. The skills of the participants was impressively wide ranging; they spanned the experimental techniques used in the study of molecular dynamics, the nature of the systems investigated and the theoretical models employed to understand the results. While much was learnt it was also recognised that much more needed to be done in order to advance our understanding of molecular dynamics in liquid Cl)'Stais.
