摘要：

Quantum yields for the products from trimethylgallium (TMG) photolysis were determined via a new method involving isotopic analysis using TMG-acetone-d6 mixtures. The following model-dependent quantum yields were obtained: monomethylgallium (MMG), 0.5; dimethylgallium (DMG), 0.2; gallium, 0.3; molecularly eliminated ethane, 0.3; free methyl, 1.5. Two new electronic absorptions at 216 and 220 nm were found and are tentatively ascribed to DMG*. © 1990.
