Abstract
Using a molecular dynamics computer simulation technique, evaporation and condensation processes of liquid methanol are studied at room temperature. We observe evaporation of a hydrogen-bonded dimer, which was experimentally suggested. The condensation coefficient (the number of ratio of condensed molecules to incident ones) seems to be less than unity as several groups predicted. Since various modes of dynamic processes at the surface are found, more careful analysis and theoretical consideration are necessary.
