Tunable diode laser measurements of N2- and O2-pressure broadening and pressure-induced shifts for 16O12C32S transitions in the ν3 band

Nitrogen and oxygen pressure broadening and pressure-induced shift coefficients for 42 transitions of 16O12C32S with quantum number m from −25 to 49 in the P and R branches of the ν3 band at 2062 cm−1 have been measured at room temperature using a high-resolution tunable diode laser spectrometer. Air-broadening and shift parameters have also been calculated from the N2 and O2 measurements. The dependence of the broadening and shifting on rotational quantum number is discussed. The results are compared to previous measurements in the ν1 and 2ν3 bands and to the parameters for the ν3 band that are reported in the HITRAN database.
