The ultraviolet photolyses of GeH3Br and GeD3Br in an argon matrix have been performed between 8 and 24°K. The major products resulting from photolysis appear to be GeH2Br and GeHBr and their deuterated counterparts. All the fundamental vibrational frequencies of these species are observed with the exceptions of one of the GeH stretches and the GeH2 and GeD2 valence bends (ν2) of GeH2Br and GeD2Br, respectively. The results of the normal coordinate and self-consistent extended Hückel calculations are consistent with the experimental observations and suggest that GeH2Br and GeHBr are pyramidal and bent, respectively. Structural and bonding properties of these species are also discussed.
