For the first time the infrared spectrum of PHD2 was recorded in the region of the PH stretching fundamental ν1 at 2324.005 cm-1 and the overtone 2ν1 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 ν1 and 2ν1 bands, which provided 316 and 248 upper energies, respectively. Since both the bands are sufficiently isolated, a standard Watson-type Hamiltonian (A-reduction, Ir-representation) 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.
