Source: Landolt-Börnstein, New Series Volume: II/19a Year: 1992 Keyword: organic compounds; molecular constants; spectroscopy; microwave spectroscopy ISBN: 3-540-54409-7 ISBN: 978-3-540-54409-8 Internet Resource: DOI:10.1007/b42304 RefComment: XI, 143 pages. 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/19a contains a general introduction and tables of rotational and centrifugal distortion constants of diamagnetic, diatomic, linear and symmetric top molecules, which specify the frequences of the rotational transitions of these types of rotor.
