Times Cited Count:2 Percentile:11.6(Physics, Atomic, Molecular & Chemical)Absorption spectra of gaseous samples containing NHD and NHD have been measured in 11580-11880 and 15280-15610 cm regions, corresponding to the 5 and 5 vibrational bands, respectively. Photoacoustic spectroscopy has been utilized for the measurement. The molecular constants of NHD in the 5 state and NHD in the 5 state have been determined by the analysis of the obtained absorption spectrum. Comparing the constants with those of the vibrational ground states, structural changes caused by the stretching excitations have been elucidated. The HND bond angles are decreased by these excitations. The dependence of the molecular constants on the stretching quantum number has been also derived by simple Birge-Sponer and Dunham analyses.
