The infrared spectral regions of the P-D stretching fundamental band v2 and the first overtone band 2v2 of PH2D were recorded with a resolution of 2.7 × 10-3 and 6.8 × 10-3 cm-1, respectively. In the analysis about 710 and 440 transitions were assigned to the v2 and 2v2 bands. These provided 358 and 268 upper rovibrational energy terms, respectively. Resonance interactions between the states (010000) and (000200) were taken into account in the Hamiltonian used to fit upper energies of the (010000) state. The rovibrational energies of the (020000) state were fitted with a Hamiltonian for an isolated vibrational state.
