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.
