✦ Synopsis

The infrared spectral regions of the P-D stretching fundamental band m 2 and the first overtone band 2m 2 of PH 2 D were recorded with a resolution of 2:7 Â 10 À3 and 6:8 Â 10 À3 cm À1 , respectively. In the analysis about 710 and 440 transitions were assigned to the m 2 and 2m 2 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.
