摘要：

Lineshape measurements of OCS rotational transitions have been carried out by using frequency modulation and comparing the experimental second harmonic signal to the computed second Fourier component of a modulated Voigt profile. The asymmetry of the spectral lines has been accounted for by adding to the lineshape model a suitable distortion term. The modulation amplitude values which provide good agreement between the experimental and the computed spectra have been found. The self-broadening coefficients of the J = 8 ← 7, 12 ← 11, and 16 ← 15 ground state transitions of OC34S and O13CS have been determined. © 1990.
