Landolt-Boernstein: Numerical Data and Functional Relationships in Science and Technology - New
4 total works
20B8
With the advent of modern instruments and theories, a considerable amount of spectroscopic information has been collected on molecules during this last decade. The infrared, in particular, has seen extraordinary activity. Using Fourier transform interferometers and infrared lasers, accurate data have been measured, often with extreme sensitivity. These data have also been analyzed and accurate molecular parameters determined. Volume II/20 "Molecular Contants mostly from Infrared Spectroscopy" is a recent Landolt-Boernstein publication series. It is made up of several subvolumes (A, B, C, D) with comprehensive compilation of critically evaluated molecular constants of diatomic (A), linear triatomic (B), other triatomic (C) and other polyatomic (D) molecules.

The introduction essentially reports molecular theories and equations, on the basis of which most of the evaluated data are established. Specific comments related to some of the molecules considered in the subvolumes II/20B1-4 are retained in the present introduction due to their possible general applicability. Additional information of practical interest (list of symbols with their definitions, units, table of conversion factors, notations for the bands and energy levels, table of energy-related units and selected fundamental constants, etc.) is also given.
The tables are preceded by an additional index to help the search for specific information. In order to keep their consistency and their optimum ability to reproduce data, molecular constants are reported when possible from the same calculation of a given set of measurements. The subvolume ends with a reference section.

20B2b
Volume II/20 provides critically evaluated data on free molecules, obtained from infrared spectroscopy and related experimental and theoretical investigations.
The volume is divided into four subvolumes, A: Diatomic Molecules, B: Linear Triatomic Molecules, C: Nonlinear Triatomic Molecules, D: Polyatomic Molecules.
Subvolume B2 contains data for CO2 (OCO) and has been split into two parts. Subvolume II/20 B2° has dealt exclusively with the normal isotopic species of carbon dioxide 12C16O16O. The present part ß deals with thirteen isotopic varieties of CO2. Subvolume B3 containing data for N2O, and further subvolumes are in preparation.

Volume II/20 provides critically evaluated data on free molecules, obtained from infrared spectroscopy and related experimental and theoretical investigations.
The volume is divided into four subvolumes, A: Diatomic Molecules, B: Linear Triatomic Molecules, C: Nonlinear Triatomic Molecules, D: Polyatomic Molecules.
The present subvolume II/20 B3 deals with the linear triatomic nitrous oxide molecule, N2O (NNO). Both the normal isotopic species 14N14N16O and eleven of its isotopic varieties have been considered in this subvolume. The tables are preceded by an additional index to help the search for specific information. Subvolume B3 contains a CD-ROM. Further subvolumes are in preparation.
