Abstract:

The B-X, C-X, and D-X emission transitions of HgCl, HgBr and HgI and the B-X transition of XeF have been photographed and analyzed for isotopically pure HgX and XeF molecules. New methods have been devised for fitting data and approximating potential curves for heavy diatomics like these molecules. Results of the analysis for these molecules offer significant improvements in their spectroscopic parameters and related properties, such as potential curves, Franck-Condon factors, dissociation energies and partition functions. Originator-supplied keywords include mercury halides, zenon fluoride, HgCl, HgBr, HgI, XeF, electronic transition lasers, electronic spectroscopy, diatomic spectroscopy, vibrational analysis, rotational analysis, emission spectroscopy, potential curves, Franck-Condon factors, partition functions.
