Infrared and microwave spectra of OCO–HF and SCO–HF
Fraser, GT., Pine, AS., Suenram, RD., Dayton, D., & Miller, RE. (1989). Infrared and microwave spectra of OCO–HF and SCO–HF. Journal of Chemical Physics, 90(3), 1330-1336. https://doi.org/10.1063/1.456074
The H–F stretching bands of the OCO–HF and SCO–HF complexes have been studied by optothermal (bolometer?detected) molecular?beam spectroscopy. Both species exhibit spectra of a quasilinear molecule red shifted from free HF by 52.1 and 57.5 cm? 1, respectively. The principal band in both molecules is accompanied by a slightly red?shifted doublet?type subsidiary band that can be interpreted as a hot band of a low frequency bending vibration or a K=1 subband of a bent molecule. Accurate doublet splittings in the ground H–F vibrational state have been measured by pulsed?nozzle Fourier?transform microwave spectroscopy.
