Electronic Ground State Constants for Molecular Hydrogen and Hydrogen Deuteride

Observed rotational and rotational-vibrational transitions for molecular H2 and HD have been combined to produce best, non-linear least-squares fits to a set of self-consistent electronic ground state molecular constants for each molecule. For H2, the effects of pressure shifts have been included. Line centers, broadening coefficients and pressure shifts are given for some 35 observed lines from the 0-0 band through the 5-0 band of H2. HD constants are based on lines observed for bands from 1-0 through the 6-0 band.
