Abstract

Sub-Doppler resolution spectroscopy of the 3ν₂ band of phosphine has been carried out using a difference-frequency-generation source referenced to an optical frequency comb and a cavity-enhanced absorption cell. Three Q-branch transitions are recorded with a linewidth of 150 kHz, but no inversion splitting is observed even though it was predicted 300 kHz in Journal of Chemical Physics, vol. 145, art. No. 091102 (2016). Transition frequencies of six Q-branch transitions have been determined with an uncertainty of 6–16 kHz.
