N2 - Melting anomalies, observed in a variety of adsorbate systems such as N2, Ar or CH4 on TiO2 and H2O absorbed in coal, Al203, zeolite, or porous glass, are shown to be manifestations of the melting characteristics of small molecular clusters. The theoretical results show not only that melting is a continuous phenomenon for small aggregates, but that for clusters consisting of ten to twenty molecules, melting may commence at temperatures considerably lower than the bulk melting point. Comparison between the theory and experimental data yields excellent agreement.
