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.

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.

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.

Abstract: Volume II/24 presents the spectroscopic data on diamagnetic and paramagnetic molecules as well as on molecular ions and radicals up to date considering the publications up to and partly including 1997. The spectroscopic information collected in this volume has been obtained principally from gas phase microwave measurements. In addition, gas phase data have been included derived from methods related to microwave spectroscopy by employing a coherent radiation source.

RefComment: VIII, 481 pages. Hardcover
Abstract: This volume contains data on the geometric parameters (internuclear distances, bond angles, dihedral angles of internal rotation etc.) of free polyatomic molecules including free radicals and molecular ions. This survey on structure data is made of four subvolume, each containing the geometric parameters determined in the gas phase either by an analysis of the rotational constants (and sometimes the vibrational constants) obtained from microwave, infrared, Raman, electronic and photoelectron spectroscopy or by an analysis of electron diffraction intensities. Most of the structures listed in the tables are for molecules in the electronic ground state, but structures for electronically excited states have also been included as far as they are available. In this third subvolume, the structure of molecules containing three for four carbon atoms are listed.
