The present subvolume provides evaluated infrared spectroscopic data on O(Ozone) and is dedicated to all available molecular constants in the electronic ground state, of the 18 isotopomers. It is made of separate chapters. The first one succinctly reports molecular theories and equations, based on which most of the evaluated data given in the other chapters are established. Title of each data chapter indicates which data is reported (vibrational states, vibrational energy, band centers, harmonic frequencies, anharmonic constants, rotational and centrifugal distortion constants, resonance coupling constants, potential energy function, force constants, dipole transition moment, integrated band intensity, line shape parameters…). The isotopic identification, the natural isotopic abundance, and the cited bibliographic references are also given in each data chapter.

H2O (HOH), Part 1 alpha

by Nathalie Picque

Published 17 January 2012

With the development of modern instruments and theories, a considerable amount of spectroscopic information is being permanently collected on molecules. The infrared, in particular, is seeing extraordinary activities. Using Fourier transform interferometers and infrared lasers, accurate data are measured often with extreme sensitivity. These data are also analyzed and precise molecular parameters determined. Volume II/20, “Molecular Constants Mostly from Infrared Spectroscopy”, is a recent Landolt-Börnstein publication series bringing together these results. It is made up of several volumes (A, B, C, D) with comprehensive compilation of critically evaluated molecular constants of diatomic (A), linear triatomic (B); nonlinear triatomic (C), and other polyatomic (D) molecules. Subvolume II/20C1 is devoted to H2O.
