✦ Synopsis
The self-and foreign (Ar, N 2 , and O 2 )-pressure effects on the submillimeter-wave absorption line profiles have been investigated for the J ¼ 26-25 and 25-24 rotational transitions of N 2 O using the AIST terahertz spectrometer. By fitting the observed absorption profiles with the Galatry functions, the integral intensity, line-center position, Lorentzian width and contraction parameter were determined for each absorption line. The obtained pressure-broadening coefficients are consistent with the literature values reported for infrared spectra. The pressure dependence of contraction parameter was determined for the self-effect. The line shifts were found to be small.
