摘要：
Using a tunable diode-laser spectrometer adapted with a low temperature cell, we have measured the H-2 line-mixing coefficients for 21 lines in the R-Q branch of the nu(2) band and in the RP and RP branches of the nu(4) 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 1093 cm(-1). The variations of these parameters with the temperature, and the rovibrational quantum numbers are discussed. (C) 2016 Elsevier Ltd. All rights reserved.
