...Diatomic Molecules provides a systematic approach to quantitative analysis of molecular spectra of diatomic molecules, in particular infrared and Raman spectra. This analysis is used to extract precise information about not only molecular structure but also its associated electric and magnetic properties. This book is unique in its methodical treatment of the subject, and in the included collection of results and extensive bibliography. The first three chapters provide a thorough explanation of an empirical basis of infrared and Raman spectra, together with the theory behind techniques employed in their analysis. Succeeding chapters outline, among other topics, wave functions and matrix elements in relation to radial functions for potential energy, dipolar moment etc., and applications of lasers. Various methods are applied in analysis of frequency data and spectral intensities, and to effects of spin and intermolecular interaction. The many subjects are discussed in depth, with reviews of topics important in future progress of experiment and theory in molecular spectroscopy. Senior undergraduate and postgraduate students in chemistry and physics will find ..Diatomic Molecules a useful adjunct to their course texts, and it will prove invaluable to all researchers in spectroscopy.

This book provides a fresh, photon‐based description of modern molecular spectroscopy and photophysics, with applications drawn from chemistry, biology, physics and materials science. The concise and detailed approach includes some of the most recent devel

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 elegant book provides a student-friendly introduction to the subject of physical chemistry. It is by the author of the very successful Basic Chemical Thermodynamics and is written in the same well-received popular style. It is concise and more compact than standard textbooks on the subject and emphasises the two important topics underpinning the subject: quantum mechanics and the second law of thermodynamics. Both topics are challenging to students because they focus on uncertainty and probability. The book explains these fundamental concepts clearly and shows how they offer the key to understanding a wide range of chemical phenomena including atomic and molecular spectra, the structure and properties of solids, liquids and gases, chemical equilibrium and the rates of chemical reactions.This revised edition has enabled improvements and corrections to be made.

Spectra of Atoms and Molecules, 2nd Edition is designed to introduce advanced undergraduates and new graduate students to the vast field of spectroscopy. Of interest to chemists, physicists, astronomers, atmospheric scientists, and engineers, it emphasizes the fundamental principles of spectroscopy with its primary goal being to teach students how to interpret spectra. The book includes a clear presentation of group theory needed for understanding the material and a large number of excellent problems are found at the end of each chapter. In keeping with the visual aspects of the course, the author provides a large number of diagrams and spectra specifically recorded for this book. Topics such as molecular symmetry, matrix representation of groups, quantum mechanics, and group theory are discussed. Analyses are made of atomic, rotational, vibrational, and electronic spectra. Spectra of Atoms and Molecules, 2nd Edition has been updated to include the 1998 revision of physical constants, and conforms more closely to the recommended practice for the use of symbols and units. This new edition has also added material pertaining to line intensities, which can be confusing due to the dozens of different units used to report line and band strengths. Another major change is in author Peter Bernath's discussion of the Raman effect and light scattering, where the standard theoretical treatment is now included. Aimed at new students of spectroscopy regardless of their background, Spectra of Atoms and Molecules will help demystify spectroscopy by showing the necessary steps in a derivation.
