Book excerpt: The energy and dynamics of excited states in a variety of anisotropic environments, including isotopically and chemically mixed crystals and molecular overlayers adsorbed on a nickel (111) surface, are investigated. The relationship between local and long-range structure and spectroscopic properties is explored. A theory for energy transfer in substitutionally disordered solids is presented. Explicit expressions for the ''diffusion'' coefficients and the energy partitioning ratios in binary systems are derived. Energy transfer between localized states is found to be facilitated by concurrent tunnelling and thermal promotion. Experimental results for triplet energy partitioning between mobile and stationary trap states as a function of mobile trap concentration in the ternary d2-1,2,4,5-tetrachlorobenzene--h2-1,2,4,5-tetrachlorobenzene--pyrazine system are analyzed. It is shown that both tunnelling and thermal detrapping contribute to triplet exciton mobility below 4.2 K. Singlet exciton migration makes an important contribution to trap equilibration before intersystem crossing to the triplet manifold. Spin coherence experiments are used to determine the energy level structure, physical geometry, and exciton dynamics of a series of impurity-induced traps in 1,2,4,5-tetrachlorobenzene. The uv spectra of pyrazine, pyridine, and naphthalene adsorbed on a nickel single crystal (111) surface are measured by spectroscopic ellipsometry at low temperatures. The excited electronic and vibronic energy levels measured are similar to bulk molecular crystal values, but pyrazine and pyridine show small, but significant deviations. The ordering of molecular overlays is observed spectroscopically and information about overlayer crystal structure is deduced. 148 references, 48 figures, 5 tables.

Available in PDF, EPUB and Kindle. Book excerpt: An up-to-date comprehensive text useful for graduate students and academic researchers in the field of energy transfers in fluid flows. The initial part of the text covers discussion on energy transfer formalism in hydrodynamics and the latter part covers applications including passive scalar, buoyancy driven flows, magnetohydrodynamic (MHD), dynamo, rotating flows and compressible flows. Energy transfers among large-scale modes play a critical role in nonlinear instabilities and pattern formation and is discussed comprehensively in the chapter on buoyancy-driven flows. It derives formulae to compute Kolmogorov's energy flux, shell-to-shell energy transfers and locality. The book discusses the concept of energy transfer formalism which helps in calculating anisotropic turbulence.

Download or read book FRET F rster Resonance Energy Transfer written by Igor L. Medintz and published by John Wiley & Sons. This book was released on 2013-10-17 with total page 824 pages. Available in PDF, EPUB and Kindle. Book excerpt: FRET – Förster Resonance Energy Transfer Meeting the need for an up-to-date and detailed primer on all aspects of the topic, this ready reference reflects the incredible expansion in the application of FRET and its derivative techniques over the past decade, especially in the biological sciences. This wide diversity is equally mirrored in the range of expert contributors. The book itself is clearly subdivided into four major sections. The first provides some background, theory, and key concepts, while the second section focuses on some common FRET techniques and applications, such as in vitro sensing and diagnostics, the determination of protein, peptide and other biological structures, as well as cellular biosensing with genetically encoded fluorescent indicators. The third section looks at recent developments, beginning with the use of fluorescent proteins, followed by a review of FRET usage with semiconductor quantum dots, along with an overview of multistep FRET. The text concludes with a detailed and greatly updated series of supporting tables on FRET pairs and Förster distances, together with some outlook and perspectives on FRET. Written for both the FRET novice and for the seasoned user, this is a must-have resource for office and laboratory shelves.

Available in PDF, EPUB and Kindle. Book excerpt: The breadth of scientific and technological interests in the general topic of photochemistry is truly enormous and includes, for example, such diverse areas as microelectronics, atmospheric chemistry, organic synthesis, non-conventional photoimaging, photosynthesis, solar energy conversion, polymer technologies, and spectroscopy. This Specialist Periodical Report on Photochemistry aims to provide an annual review of photo-induced processes that have relevance to the above wide-ranging academic and commercial disciplines, and interests in chemistry, physics, biology and technology. In order to provide easy access to this vast and varied literature, each volume of Photochemistry comprises sections concerned with photophysical processes in condensed phases, organic aspects which are sub-divided by chromophore type, polymer photochemistry, and photochemical aspects of solar energy conversion. Volume 34 covers literature published from July 2001 to June 2002. Specialist Periodical Reports provide systematic and detailed review coverage in major areas of chemical research. Compiled by teams of leading authorities in the relevant subject areas, the series creates a unique service for the active research chemist, with regular, in-depth accounts of progress in particular fields of chemistry. Subject coverage within different volumes of a given title is similar and publication is on an annual or biennial basis.

Available in PDF, EPUB and Kindle. Book excerpt: Resonance Energy Transfer The resonance transfer of energy between molecules, or between sites within a large molecule, plays a central role in many areas of modern chemistry and physics. In biophysics, for example, this process defines the migration of excitation energy within photosynthetic systems (commonly the Frster mechanism). Another important area is in crystals, laser and other laser materials. Resonance Energy Transfer contains a large amount of cutting-edge research which has never before appeared in book form. It is the first comprehensive modern survey of the field, offering a broad, yet detailed view of the mechanisms of energy transfer. The broad range of applications of fluorescence and fluorescence energy transfer to studies in molecular biology and biotechnology ensures that resonance energy transfer will be a vital component of the new science and technology of the next millenium. This book is written for those working with materials, both experimentally and theoretically, as well as for biophysicists and biochemists interested in studying protein structure and dynamics.

This book was released on 2011-11-01 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Exploration of Supramolecular Systems and Nanostructures by Photochemical Techniques provides a comprehensive view of the most commonly used photochemical and photophysical techniques and their applications to the study of supramolecular systems. Optical inputs are extremely powerful in the study of nanostructures since they can be used both to “read” the state of the system and to provide it energy to work. After a brief introduction to the realm of photochemistry, electronically excited state formation and the different pathways of excited state deactivation, the book focuses on the theoretical basis and the practical aspects related to the most widely used photophysical and photochemical techniques, from absorption to time-resolved emission techniques with polarized light. Each chapter illustrates an example of the application of that particular technique to the study of a supramolecular system. The Exploration of Supramolecular Systems and Nanostructures by Photochemical Techniques not only discusses the latest advances of the field of supramolecular photochemistry but it also offers technical and operative details useful in the laboratory. It is therefore suitable for both the novice and the expert.
