In older days chemists mixed starting materials in a flask and took the resul tants out of it after a while, leaving all the intermediate steps uncleared as a sort of black box. One had to be content with only changing temperature and pressure to accelerate or decelerate chemical reactions, and there was almost no hope of initiating new reactions. However, a number of new techniques and new methods have been introduced and have provided us with a clue to the examination of the black box of chemical reaction. Flash photolysis, which was invented in the 1950s, is such an example; this method has been combined with high-resolution electronic spectroscopy with photographic recording of the spectra to provide a large amount of precise and detailed data on transient molecules which occur as intermediates during the course of chemical reac tions. In 1960 a fundamentally new light source was devised, i. e. , the laser. When the present author and coworkers started high-resolution spectroscopic stud ies of transient molecules at a new research institute, the Institute for Molecu lar Science in Okazaki in 1975, the time was right to exploit this new light source and its microwave precursor in order to shed light on the black box.

Book excerpt: Over recent years electronic spectroscopy has developed significantly, with key applications in atmospheric chemistry, astrophysics and astrochemistry. High Resolution Electronic Spectroscopy of Small Molecules explores both theoretical and experimental approaches to understanding the electronic spectra of small molecules, and explains how this information translates to practice. Professors Geoffrey Duxbury and Alexander Alijah present the links between spectroscopy and photochemistry, and discuss theoretical treatments of the interaction between different electronic states. They provide a thorough discussion of experimental techniques, and explore practical applications. This book will be an indispensable reference for graduate students and researchers in physics and chemistry working on theoretical and practical aspects of electronic spectra, as well as atmospheric scientists, photochemists, kineticists and professional spectroscopists.

Available in PDF, EPUB and Kindle. Book excerpt: This handbook presents structural data on free polyatomic molecules. Since the structure of molecules defines the chemical, physical and biological properties of matter, this information is crucial for understanding, explaining and predicting chemical reactions and biochemical processes, developing new drugs and materials as well as studying interstellar media. Covering the structural data published between 2009 and 2017, this book supplements the previous Landolt–Börnstein volumes “Structure Data of Free Polyatomic Molecules” (eds. K. Kuchitsu, N. Vogt, M. Tanimoto), which included data from the literature published up to 2008. It systematizes and describes peculiarities of molecular structures for about 1000 compounds studied mainly by gas-phase electron diffraction and rotational spectroscopy. All structures are given in three-dimensional representations.

Available in PDF, EPUB and Kindle. Book excerpt: 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 was released on 2013-03-08 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 1970s, researchers in Canada, the Soviet Union and the United States discovered that powerful infrared laser pulses are capable of dissociating mole cules such as SiF4 and SF6' This result, which was so unexpected that for some time the phenomenon of multiple-photon dissociation was not recognized in many cir cumstances in which we now know that it occurs, was first publicized at a time when the possibility of using lasers for the separation of isotopes had attracted much attention in the scientific community. From the mid-1970s to the early 1980s, hun dreds of experimental papers were published describing the multiple-photon absorp tion of C02 laser pulses in nearly every simple molecule with an absorption band in the 9 - 11 jJm region. Despite this impressive volume of experimental results, and despite the efforts of numerous theorists, there is no agreement among re searchers in the field on many fundamental aspects of the absorption of infrared laser light by polyatomic molecules. This book is devoted to reviells of the experimental and theoretical research that provides the foundations for our current understanding of molecular multiple photon exc itat i on, and to rev i ews of research that is pert i nent to the 1 aser sep aration of isotopes.

Book excerpt: 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.
