TEMPERATURE DEPENDENT FOREIGN GAS BROADENING COEFFICIENTS OF THE R(42) AND P(13) LINES IN THE v_1 BAND OF N_2O

摘要

Foreign gas broadening coefficients of the R(42) and P(13) transitions in the v_1 band of N_2O near 1285 cm~(-1) have been measured at a spectral resolution of ～5 x 10~(-4)cm~(-1) using tunable diode laser spectrometry. Ar, He, N_2, and O_2 were used as the broadening gases. In order to determine the temperature dependence of the broadening coefficients, data were obtained at temperatures ranging from 154 to 294 K.
