Infrared Emission Spectroscopy of Bismuth Monohydride and Bismuth Monodeuteride

The high-resolution infrared emission spectra of bismuth monohydride and bismuth monodeuteride have been observed by Fourier transform spectroscopy. Gaseous BiH and BiD were produced by the direct reaction of the metal with hydrogen and deuterium, respectively. About 120 lines with v = 1 → 0 to v =...

Summary:The high-resolution infrared emission spectra of bismuth monohydride and bismuth monodeuteride have been observed by Fourier transform spectroscopy. Gaseous BiH and BiD were produced by the direct reaction of the metal with hydrogen and deuterium, respectively. About 120 lines with v = 1 → 0 to v = 3 → 2 for each isotopomer have been measured. Dunham coefficients, Y ij , have been derived in separate fits for the two molecules. In addition all data have been used in a combined fit to yield the mass-reduced Dunham constants, U ij .
