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.

Abstract: The volume II/27 has been divided into three subvolumes according to the classes of compounds: Subvolume A: Diamagnetic susceptibility and magnetic anisotropy of inorganic and organometallic compounds; Subvolume B: Diamagnetic susceptibility of organic compounds, oils, paraffins and polyethylenes; Subvolume C: Diamagnetic susceptibility and magnetic anisotropy of organic compounds. The data presented in this volume are based on the literature survey of the chemical abstracts up to 2005. The calculated values of diamagnetic susceptibility of organic compounds in the present subvolume II/27B are presented along with their experimental values. They have been calculated with the use of structural parameters in structural formula by using different theoretical methods available in the literature.

Abstract: Volume III/31 continues the compilation of nuclear quadrupole resonance spectroscopy data of solid substances which started in with volume III/20 in 1987 covering the literature from the beginning of nuclear quadrupole resonance spectroscopy in 1951 to 1982 and containing the data for 8000 substances in the solid state, distributed among three subvolumes III/20 a, b, and c. Volume III/31 covers the literature published in the period from the end of 1982 through the end of 1989. Included are the data for substances studied for the first time, as well as data for substances already present in the previous volume III/20 if the data published there could be completed or improved by new studies. In total there are 2500 substances in volume III/31, showing the scope and significance of nuclear quadrupole resonance spectroscopy up to recent times.
