Gas-phase Raman spectra of some dihalides of zinc and mercury, of ‘GaCl2’ and of GaCl2Br and GaBr2Cl

Abstract

The Raman spectra of HgX₂(X = Cl, Br, or l), ZnX₂, and HgXY (X,Y= Cl, Br, or l) are reported for the gaseous monomeric species. In no case was a deformation mode identified, although formally this mode is active for linear HgXY. When the compound ‘GaCl₂’ was examined in the gas phase only bands due to GaCl and GaCl₃ were identified. GaBr₂Cl and GaCl₂Br were identified in high-temperature gas-phase Raman studies of mixtures of GaCl₃ and GaBr₃.
