, 1995: Collisional excitation of interstellar sulfur dioxide. Astrophys. J. Supp. Series, 100, 213-216, doi:10.1086/192216.
Rotational excitation rates for sulfur dioxide in collisions with He atoms at temperatures from 25-125 K, obtained from theoretical calculations by Palma (1987), have been reanalyzed in terms of corrected asymmetric top rotational wavefunctions.
