Abstract

The high resolution spectrum of a phosphine gas mixture containing PHD 2 was recorded at room temperature in the 12 550-12 770 cm -1 region. A high sensitivity laser photoacoustic spectrometer consisting of a longitudinal resonant cell coupled to a Ti:sapphire ring laser was employed. More than 600 transitions were assigned to the 6ν1 overtone band of PHD2 up to Jmax = 20, Ka max = 6. A Hamiltonian model developed up to the octic centrifugal distortion terms was used. Seven rotational and centrifugal distortion parameters were fitted, the other ones being fixed to their values linearly extrapolated from ν1 and 2ν1. The derived parameters reproduce the initial data within the experimental uncertainties. The isolated character of the P-H bond is confirmed.
