Book Description
Much of what we know about atoms, molecules, and the nature of matter has been obtained using spectroscopy over the last one hundred years or so. In this book we have collected together twenty chapters by eminent scientists from around the world to describe their work at the cutting edge of molecular spectroscopy. These chapters describe new methodology and applications, instrumental developments, and theory which is taking spectroscopy into new frontiers. The range of topics is broad. Lasers are utilized in much of the research, but their applications range from sub-femtosecond spectroscopy to the study of viruses and also to the investigation of art and archeological artifacts. Three chapters discuss work on biological systems and three others represent laser physics. The recent advances in cavity ringdown spectroscopy (CRDS), surface enhanced Raman spectroscopy (SERS), two-dimensional correlation spectroscopy (2D-COS), and microwave techniques are all covered. Chapters on electronic excited states, molecular dynamics, symmetry applications, and neutron scattering are also included and demonstrate the wide utility of spectroscopic techniques. - Provides comprehensive coverage of present spectroscopic investigations - Features 20 chapters written by leading researchers in the field - Covers the important role of molecular spectroscopy in research concerned with chemistry, physics, and biology

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
Rasmus Brogaard's thesis digs into the fundamental issue of how the shape of a molecule relates to its photochemical reactivity. This relation is drastically different from that of ground-state chemistry, since lifetimes of excited states are often comparable to or even shorter than the time scales of conformational changes. Combining theoretical and experimental efforts in femto-second time-resolved photoionization Rasmus Brogaard finds that a requirement for an efficient photochemical reaction is the prearrangement of the constituents in a reactive conformation. Furthermore, he is able to show that by exploiting a strong ionic interaction between two chromophores, a coherent molecular motion can be induced and probed in real-time. This way of using bichromophoric interactions provides a promising strategy for future research on conformational dynamics.
