Book Description
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 Description
Significant accomplishments were made under the program of dynamical spectroscopy, aimed at elucidating details of chemical dynamics in condensed media. In fact, there now is a well-defined field of multi-dimensional spectroscopy, entirely aimed at the essence of what we had proposed. In the same natural vain of evolution, we developed the rather powerful technique of Time and Frequency Resolved Coherent Anti Stokes Raman Scattering (TFRCARS), as a tool that goes beyond the interrogation of interactions and molecular dynamics in condensed media. This four-wave mixing scheme, with transform limited detection of evolving coherences, can be regarded as a complete experiment in the creation, manipulation, and interrogation of quantum coherences. As such, it foreshadows useful quantum control, be it for chemical or computational purposes. A significant part of our present effort is aimed at devising and implementing control with shaped pulses to demonstrate computational algorithms in the laboratory. The original inspiration for developing TFRCARS was our aim to manipulate molecular wavepackets in regions where direct pumping could not be achieved, due to the inaccessible Franck-Condon factors. The target of those studies was the detailed dissection of non-adiabatic dynamics in the condensed phase prototype of solvated molecular iodine. While significant progress has been made toward this end, both direct experimentation and theoretical understanding of this process remain somewhat illusive. Highlights of advances made in theory and experiment are given based on some 20 published works that have appeared during this funding period, as a result of partial or total support by the grant.

Book Description
Since the first stimulated emission pumping (SEP) experiments more than a decade ago, this technique has proven powerful for studying vibrationally excited molecules. SEP is now widely used by increasing numbers of research groups to investigate fundamental problems in spectroscopy, intramolecular dynamics, intermolecular interactions, and even reactions. SEP provides rotationally pre-selected spectra of vibrationally highly excited molecules undergoing large amplitude motions. A unique feature of SEP is the ability to access systematically a wide variety of extreme excitations localized in various parts of a molecule, and to prepare populations in specific, high vibrational levels. SEP has made it possible to ask and answer specific questions about intramolecular vibrational redistribution and the role of vibrational excitation in chemical reactions.

Book Description
Condensed-Phase Molecular Spectroscopy and Photophysics An introduction to one of the fundamental tools in chemical research—spectroscopy and photophysics in condensed-phase and extended systems Condensed-Phase Molecular Spectroscopy and Photophysics comprehensively covers radiation-matter interactions for molecules in condensed phases along with metallic and semiconductor nanostructures, examining optical processes in extended systems such as metals, semiconductors, and conducting polymers and addressing the unique optical properties of nanoscale systems. The text differs from others through its emphasis on the molecule-environment interactions that strongly influence spectra in condensed phases, including spectroscopy and photophysics of molecular aggregates, molecular solids, and metals and semiconductors, as well as more modern topics such as two-dimensional and single-molecule spectroscopy. To aid in reader comprehension, the text includes case studies and illustrated examples. An online manual with solutions to the problems in the book is available to all readers on a companion website. Condensed-Phase Molecular Spectroscopy and Photophysics begins with an introduction to quantum mechanics that sets a solid foundation for understanding the text’s subsequent topics, including: Electromagnetic radiation and radiation-matter interactions, molecular vibrations and infrared spectroscopy, and electronic spectroscopy Photophysical processes and light scattering, nonlinear and pump-probe spectroscopies, and electron transfer processes Basic rotational spectroscopy and statistical mechanics, Raman scattering, 2D and single-molecule spectroscopies, and time-domain pictures of steady-state spectroscopies Time-independent quantum mechanics, statistical mechanics, group theory, radiation-matter interactions, and system-bath interactions Atomic spectroscopy, photophysical processes, light scattering, nonlinear and pump-probe spectroscopies, two-dimensional spectroscopies, and metals and plasmons Written for researchers and upper-level undergraduate and graduate courses in physical and materials chemistry, Condensed-Phase Molecular Spectroscopy and Photophysics is a valuable learning resource that is uniquely designed to equip readers to solve a broad array of current problems and challenges in the vast field of chemistry.

Book Description
Russian contributors provide a synthesis of ideas drawn from dielectric, magnetic and elastic relaxation. Divided into three sections, the book commences with dielectric and related processes in simple liquids. Part two deals with the structure and dielectric relaxation of aqueous solutions. Lastly, it addresses magnetic and dielectric relaxation in liquid crystals and elastic relaxation in orientable polymers.
