Evaporation and condensation processes at a liquid surface of methanol were investigated at room temperature with a microcanonical molecular dynamics computer simulation technique. The condensation coefficient (the number ratio of condensed molecules to incident ones) was estimated by comparing two types of autocorrelation functions, and found to be less than unity, which is in qualitative agreement with experiments. A variety of complex dynamic phenomena were observed at the surface.
