ABSTRACT
Photoelectron (PE) spectra of ClH[SUP-,SUB2] and ClD[SUP-,SUB2] were measured at 299 nm (4.154 eV). Photodetachment of these anions accesses the prereactive van der Waals well on the ground state Cl+ H[SUB2] potential energy surface, as well as the low-lying spin-orbit excited states resulting from the interaction of Cl and Cl* with H[SUB2]. The PE spectra are dominated by two relatively narrow peaks corresponding to transitions to the neutral Cl·H[SUB2] and Cl*· H[SUB2] complexes. The energetics and widths of these features are interpreted in terms of the properties of the anion and neutral potential energy surfaces.

    SiO2 films can be grown on SiC by oxidation of the clean SiC surfaces. During the oxidation process carbon atoms have to leave the crystal. This occurs by outdiffusion of CO molecules from the reaction front through the growing film. Carbon atoms remaining at the interface or in the oxide film...
