Abstract
SOME years ago we showed1 that the melting points of molecular layers spread over solid surfaces are lower than the melting points of the bulk substances. The melting point may be lower by as much as 30° C and depends on the nature of the substance, the number of molecular layers spread over the solid surface and the nature of the solid support. Monolayers show maximum lowering, while after a coverage of four to ten layers the melting points reach their bulk values. This phenomenon is a general property of all substances.
