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.

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.

The unique behavior of the "liquid state", together with the richness of phenomena that are observed, render liquids particularly interesting for the scientific community. Note that the most important reactions in chemical and biological systems take place in solutions and liquid-like environments. Additionally, liquids are utilized for numerous industrial applications. It is for these reasons that the understanding of their properties at the molecular level is of foremost interest in many fields of science and engineering. What can be said with certainty is that both the experimental and theoretical studies of the liquid state have a long and rich history, so that one might suppose this to be essentially a solved problem. It should be emphasized, however, that although, for more than a century, the overall scientific effort has led to a considerable progress, our understanding of the properties of the liquid systems is still incomplete and there is still more to be explored. Basic reason for this is the "many body" character of the particle interactions in liquids and the lack of long-range order, which introduce in liquid state theory and existing simulation techniques a number of conceptual and technical problems that require specific approaches. Also, many of the elementary processes that take place in liquids, including molecular translational, rotational and vibrational motions (Trans. -Rot. -Vib. coupling), structural relaxation, energy dissipation and especially chemical changes in reactive systems occur at different and/or extremely short timescales.

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.
