We calculate the difference in the surface potentials between the free surface of a liquid metal and the same metal in an ideally polarizable interface at the point of zero charge. This difference, δXm, is due to the deformation of the electronic cloud of the metal by the solvent molecules. The simple model used for the free (metal-metal vapor) surface yields qualitatively correct work functions for a number of metals (Hg, Cd, In, Zn, Pb, Ga, A1). Two simple ways to model the metal-solvent interaction are proposed and calculations of δXm made for each. One, the dielectric film model, considers …

University of the Pacific Theses and Dissertations
We have studied the reactions of O(1D) with CC13F, CC12F2 and CC1F3 in CO2, SF6 and N2O matrices, and in neat mixtures. Photolysis of cryogenic mixtures of ozone and the chlorofluoromethanes in various matrix hosts resulted in production of O(1D) which migrated through the matrix to react with the Freon molecules. Products were detected by infrared spectroscopy of the matrix deposits, with assignments confirmed by comparison of 16O and 18O absorption bands with literature values. Evidence for oxygen atom insertion into a C-C1 …

Process for the preparation of 1,2,4-triazole comprises contacting hydrazine or its aqueous solutions with at least about 2.5 moles of formamide at a temperature of 140° to 210° C. and then recovering the resultant 1,2,4- triazole in yields of 92-98% with 94-98% purity. The formamide is maintained in an excess over about the 2.5 molar amount consumed in the reaction with the hydrazine. Recovery steps for isolating the 1,2,4-triazole are disclosed.
