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.

The book reviews the results of vibration-rotational spectroscopy of molecules obtained recently by combining modern computational methods of quantum chemistry with the new techniques of high-resolution rotational and vibration-rotational spectroscopy. It shows for example that the tunneling vibration-rotational spectroscopy of the van der Waals complexes provides a new look at intermolecular forces while the high precision and sensitivity of the submillimeter-wave and Fourier transform microwave spectroscopy make it possible to study complex rotational spectra of molecules in excited vibrational states. New results of high level ab initio quantum chemical computations of vibrational and rotational energy levels and dipole moment functions of unusual molecules will be discussed together with the recent discovery of clustering of energy levels in asymmetric tops. Group theoretical analysis of floppy molecules, especially the tunneling effects in nonrigid molecules, will also be discussed.

This book describes the manipulation of molecular properties, such as orientation, structure, and dynamics, of small molecules and molecular clusters isolated in cold inert matrices by using unprecedentedly strong external electrostatic fields. Manipulation of molecules with controllable external forces is a dream of chemists. Molecules are inherently quantum-mechanical systems, control of which potentially can lead to quantum technology, such as quantum sensing and computing. This book demonstrates a combination of the ice film nanocapacitor method and the matrix isolation technique enabled the application of intense external dc electric fields across the isolated molecules and molecular clusters. Changes in molecular states induced by fields were monitored by means of vibrational spectroscopy. Also, the book presents manipulations of the inversion tunneling dynamics of ammonia molecule and the dislocation of acidic proton in hydrogen chloride–water complex. The book shows that the vibrational spectroscopy with the aid of unprecedentedly strong dc electric field can provide rich information on the electrostatic behaviors of molecules and molecular clusters, which underlie the understanding of intermolecular processes and molecular manipulation.

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
