Gas-Phase Infrared Spectra of HOF and DOF

Abstract

The infrared spectra of HOF and DOF in the gas phase have been studied. From the analysis of rotational subbands, the fundamental frequencies are determined to be 3578.5, 1354.8, and 889.0 cm⁻¹ for HOF; and 2643.5, 1003.9, and 891.1 for DOF. The respective values of the constants $\mathrm{(A″\; -\; B̄″)}$ and $\mathrm{B̄″}$ are 18.37 and 0.86 cm⁻¹ for HOF, and 9.79 and 0.81 cm⁻¹ for DOF.
