Molecular Jet Study of the Solvation of Toluene by Methane, Ethane, and Propane.

Abstract

The spectroscopic study of van der Waals (vdW) clusters in a molecular jet supersonic expansion has greatly increased our understanding of these species. Additionally, clusters composed of an aromatic molecule (solute) surrounded by small hydrocarbons (solvent) have been discussed as models have been focused on relatively small clusters with few solvent molecules: geometries, energetics, and energy dynamics have all been explored in these vdW systems. Two color time of flight mass spectroscopy studied of toluene solvated by methane, ethane, and propane in a supersonic molecular jet have been carried out. This work is quite similar to the studies in the preceding paper on benzene: the conclusions and finding in the benzene investigation are strengthened and elaborated. The comparison of calculations and experiments has yielded information on binding energy, geometry and spectral shift. A strong correlation is found between observed cluster transition intensity and cluster nucleation processes and a tentative nucleation scheme for the molecular jet formation of solute-solvent clusters is presented.
