Résumé

Using a tunable diode-laser spectrometer adapted with a low temperature cell, we have measured the H₂ line-mixing coefficients for 21 lines in the ^QR branch of the ν₂ band and in the ^PP and ^RP branches of the ν₄ band of phosphine (PH₃) at low temperature. These coefficients were determined using a multi-pressure fitting procedure that accounts for the apparatus function, the Doppler and the collisional effects. These lines with J values ranging from 2 to 11 and K from 0 to 9 are located in the spectral range from 1016 to 1093cm^-1. The variations of these parameters with the temperature, and the ro-vibrational quantum numbers are discussed.
