✦ Synopsis

For the first time the infrared spectrum of PHD 2 was recorded in the region of the PH stretching fundamental ν 1 at 2324.005 cm -1 and the overtone 2ν 1 at 4563.634 cm -1 with a resolution of 4.2 × 10 -3 cm -1 and 8.8 × 10 -3 cm -1 , respectively. In the analyses about 1340 and 1020 transitions were assigned to the corresponding ν 1 and 2ν 1 bands, which provided 316 and 248 upper energies, respectively. Since both the bands are sufficiently isolated, a standard Watson-type Hamiltonian (A-reduction, I rrepresentation) was employed. The obtained sets of spectroscopic parameters correlate very well both with each other, and with the corresponding parameters of the ground vibrational state.

High-resolution FTIR data of carbonyl fluoride in the region of the C-O stretch n 1 fundamental have been analyzed. Satisfactory interpretation of the spectral data required a rigorous analysis that involved the inclusion of Fermi resonance with the 2n 2 state and Coriolis interaction with the 2n 3
