Paper Abstract

The vapor spectra of the title compounds were recorded between 50 and 700 cm-1 with an evacuable FT-IR spectrometer by transmission and emission techniques. Special vapor cells were made of nickel and fitted with windows of diamond. Quite analogous spectra were recorded in absorption and emission. At tempratures higher than 300°C the emission spectra had the better quality above 100 cm-1. The equilibria between the dimer and monomer species were studied as a function of temperature. Seven of eight IR active dimer (D2b) bands were assigned. For AlI3 and GaC13 monomers (D3h), the three IR active modes were found. Force fields for the dimers were derived by combination with Raman vapor data.
