Download or read book Energy Dissipation in Molecular Systems written by André Tramer and published by Springer Science & Business Media. This book was released on 2005-12-27 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy Dissipation in Molecular Systems analyzes experimental data on the redistribution and dissipation of energy injected into molecular systems by radiation or charged particles. These processes, competing with such practically important relaxation channels as chemical reaction or stimulated emission (laser action), are the primary focus in this monograph. Among other topics, the book treats vibrational redistribution and electronic relaxation in isolated molecules and the effects of inter-molecular interactions (collisions, complex formation, solvent effects) on the relaxation paths. Primary photo-chemical processes (such as isomerization, proton or hydrogen-atom transfer, electron transfer and ionization) are also treated as particular cases of vibrational or electronic relaxation. Only a basic knowledge of quantum mechanics and spectroscopy is assumed and calculations are kept to a strict minimum, making the book more accessible to students.
Download or read book Dynamics at Surfaces Understanding Energy Dissipation and Physicochemical Processes at the Atomic and Molecular Level written by Marco Sacchi and published by Frontiers Media SA. This book was released on 2024-04-26 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy release to solid interfaces following chemical reactions is ubiquitous in a vast range of phenomena. Energy dissipation and dynamical disorder (surface entropy), surface friction and molecular diffusion control the rates of heterogeneous catalytic reactions, the efficiency of novel technology, lubrication as well as materials growth including self-assembly and nano-structures. Yet we understand little about the underlying nature of these mechanisms. Fundamentally, energy dissipation including interactions with phonons and electron-hole pairs determines the lifetime of molecular vibrations and rotations as well as the decoherence rate of quantum states. These processes form a central point for many aspects in physical chemistry, are embedded in the mechanisms that control surface dynamical processes and are critical factors in catalysis. They are equally relevant for physicochemical processes in the Earth's atmosphere and astrochemistry occurring on cosmic dust grains.
Download or read book Charge and Energy Transfer Dynamics in Molecular Systems written by Volkhard May and published by John Wiley & Sons. This book was released on 2011-04-27 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 3rd edition has been expanded and updated to account for recent developments, while new illustrative examples as well as an enlarged reference list have also been added. It naturally retains the successful concept of its predecessors in presenting a unified perspective on molecular charge and energy transfer processes, thus bridging the regimes of coherent and dissipative dynamics, and establishing a connection between classic rate theories and modern treatments of ultrafast phenomena. Among the new topics are: - Time-dependent density functional theory - Heterogeneous electron transfer, e.g. between molecules and metal or semiconductor surfaces - Current flows through a single molecule. While serving as an introduction for graduate students and researchers, this is equally must-have reading for theoreticians and experimentalists, as well as an aid to interpreting experimental data and accessing the original literature.

Download or read book Characterization of Liquids Nano and Microparticulates and Porous Bodies using Ultrasound written by Andrei S. Dukhin and published by Elsevier. This book was released on 2010-06-03 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two key words define the scope of this book: 'ultrasound' and 'colloids'. Historically, there has been little real communication between practitioners in these two fields. Although there is a large body of literature devoted to ultrasound phenomenon in colloids, there is little recognition that such phenomena may be of real importance for both the development and applications of colloid science. On the other side, colloid scientists have not embraced acoustics as an important tool for characterizing colloids. The lack of any serious dialogue between these scientific fields is the biggest motivation behind this book. Covers in detail this multidisciplinary field combining acoustics, electroacoustics, colloid science, analytical chemistry and rheology Provides a bibliography with more than 1,000 references Presents theories and their experimental verification, as well as analysis of the methods and hardware pertaining to applications such as pharmaceuticals, ceramics, and polymers

Download or read book Rates and Mechanisms of Energy Dissipation and the Structure of Molecular Solids written by M. A. El-Sayed and published by . This book was released on 1984 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research carried out covered a number of research areas. The use of spins of the lowest triplet state was studied as a probe of intramolecular intersystem energy transfer in molecules. The interplay between singlet and triplet of different electronic nature was quantitatively examined (publications 1-5, 8 and 13). Nonradiative processes in the gas phase and in solution were studied in publications 7,10,11 and 14. Spectral diffusion studies due to intermolecular energy transfer in solids were made for both spin transitions (publications 15 and 16), electronic transitions of rare earth ions in glasses (publications 6,17,18 and 20) and singlet-triplet electronic transitions in orientationally disordered solids (publications 19, 21-23). In all these studies, the mechanisms of the energy transfer processes involved are investigated in terms of the interaction coupling involved.
