The disappearance of the rotational rainbow in the scattering of unexcited diatomic molecules from a smooth rigid surface due to initial vibrational and rotational excitation and surface corrugation has been studied by classical trajectory calculations. The ratio of vibrational to rotational excitation in initially unexcited molecules strongly increases with increasing impact energy and increasing surface hardness.
