Abstract

The lowest-lying overtone (2v2) and combination (v2 + v4) bands of phosphine have been investigated for the first time with a Fourier transform spectrometer with 0.01-cm-1 resolution. A least-squares fit which includes Coriolis coupling parameters has been performed on both bands simultaneously. The resulting constants fit 400 transitions with a standard deviation of 0.05 cm-1. Rotational parameters for the excited states and vibrational frequencies are obtained from the analysis.
