Abstract: Volume II/19 Molecular Constants mostly from Microwave, Molecular Beam and Sub-Doppler Laser Spectroscopy is a supplement to the earlier volumes II/4, II/6, and II/14. The slight change in the title reflects current trends in the applications of spectroscopic methods. Together, the four volumes collect all the critically evaluated data published up to 1989/90 on constants of free molecules obtained by classical and modern spectroscopy. Volume II/19 is divided into four parts to record the growing number of investigations, especially in the microwave and millimeter wave regions, where modern techniques like Fourier Transform Microwave Spectroscopy have made new objects of interest such as molecular complexes and clusters accessible to study. Subvolume II/19b contains corresponding data on diamagnetic asymmetric top molecules.

Subvolume II/19c contains tables for diamagnetic molecules giving further spectroscopic parameters: quadrupole coupling constants, potential barriers, and data from Stark and Zeeman effect measurements.

Internet Resource: DOI:10.1007/b19948
RefComment: 170 figs., XII, 578 pages. Hardcover
Abstract: The data compiled refer to susceptibility measurements (susceptibility, Curie-constants, magnetic moments, transition temperatures) and ESR-measurements (g-factors and other parameters of the applied spin Hamiltonian). In volume II/2 the literature from 1899 up to 1964 has been considered. Volume II/8 supplements volume II/2, taking into account the data on magnetic susceptibilities and ESR parameters published in the p eriod 1964 to 1968. The following subvolumes II/10,II/11, II/12 supplement data up to 1974.

RefComment: IX,677 pages. Hardcover
Abstract: Nuclear Quadrupole Resonance Spectroscopy has become a standard method for structural research in molecular and solid state physics as well as for different branches of chemistry. The volumes cover data for more than 8,000 substances in the solid state. Data for free molecules have been published in volumes II/14 and II/15 of the New Series. The tables are arranged according to the atomic number of the elements.

RefComment: VII, 242 pages. With CD-ROM. Hardcover
Abstract: This volume provides a comprehensive and evaluated compilation of nuclear magnetic resonance data. Chemical shifts and coupling constants of boron-11 and phosphorus-31 (subvol. A), fluorine-19 and nitrogen-15 (subvol. B), hydrogen-1 (subvol. C), and carbon-13 (subvol. D) compounds are tabulated together with the gross- and structure formulas and the most readily available solvents. Due to the large amount of the data merely chemical shifts are presented in the printed versions, and all the data, chemical shifts and coupling constants are provided on CO-ROM's.
