Widths of Rotational Lines of an Asymmetric-Top Molecule SO2. II. Broadening by a Quadrupolar Gas

The widths of six rotational lines of SO₂ broadened by N₂ have been measured. The linewidths have also been calculated theoretically on the basis of the Anderson theory and the relative importance of different interaction mechanisms has been assessed. The agreement of the $J_i$ dependence of the calculated linewidths with that of the measured linewidths is not quite satisfactory.
