Summary abstract: studies of small clusters. Relationship to understanding nucleation and surfaces
Using high-pressure mass spectrometric technique, details of the primary clustering steps leading to the nucleation of bulk liquid from the vapor are obtained by direct observation of the equilibrium cluster distribution. Results for a large number of systems have been determined, including clusters of neutral inorganic molecules and clusters of different molecules about ions. Determination of enthalpy and entropy values from these data allow one to extract information on the strengths of bonds and orientation of molecules within these clusters through correlation with the results of classical and molecular theories. Observations of mixed cluster species are proving to be of interest in the study of solvation phenomena, and because of their similarity to entities observed in surface desorption studies, are also relevant to surface science. In addition, microclusters are good prototypes for elucidating the details of ordering and structures analogous to those existing at interfaces. This paper is devoted to a review of results.
