Rotational excitation in molecule-su&m scattering is analyzed in a simple quantum two-dimensional model. The true molecule-smface potential is replaced by a hard-core ellipsokt. The model accurately describes the dominaut features of the transition probability distribution. Tbk is demonstrated by comparing rotational transition probabitities calculated from our mudel with the resutts of IOS calculations of Voges and Schinke using realistic potential. The model predicts a new scaling property mnmrning the anisotropy parameter of the potential surfam. 1. introduction A rapidly growing amount of experimental information regarding rotational energy transfer in moleculesurface collisions [l-l I] prompted a number of the-
