WATER VAPOR CONDENSATION. CLASSICAL AND QUANTUM APPROACH
Formation process of condensation’s initial nucleuses is one of the most difficult and incompletely determinate problems in new phase formation theory. These nucleuses are able to have a small size and consist only of some molecules, called “clusters” or micro-cluster. Micro-cluster is the smallest units included from two to hundred and more atoms. Modern quantum-chemical methods let to find an inertia moment, frequencies of intermolecular and intermolecular oscillations in the clusters and their dissociation energy. On the basis of these calculations it’s possible to calculate all the thermodynamic and also kinetic characteristics of the clusters. The clustered method underlies in thermodynamic of natural gas components. In this paper compared the two theories in order to find the nucleation rate of water- the classical and quantum mechanical.
