摘要：

We show that the population of the rotational degrees of freedom of gas molecules affects their adsorption probability also for a physisorbed state. The effect, expected to be very general, is demonstrated for the case of ethylene interaction with Ag(001), when the physisorption probability is suppressed for molecules produced with a hot nozzle, characterized by a substantially larger average rotational quantum number.
