Palma, A., 1987: Collisional excitation of interstellar sulfur dioxide. Astrophys. J. Supp. Ser., 64, 565-579, doi:10.1086/191209.

We have computed state-to-state rotational excitation rates for the asymmetric top molecule SO2 in collisions with low-energy He atoms. The intermolecular forces were obtained from an electron gas model, and collision dynamics were treated with the infinite-order sudden approximation. The total excitation rate is probably accurate to better than 50%; however, individual state-to-state rates may be in error by factors of 2 or 3, and some smaller rates may be accurate only to an order of magnitude. Present results are expected to reflect within the same level of accuracy rates for excitation by collisions with H2 molecules.
