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
三甲基镓(TMG)光解产物的量子产率是通过一种新的方法确定的,该方法涉及使用TMG-丙酮-d 6混合物进行同位素分析。获得了以下与模型有关的量子产率:单甲基镓(MMG),0.5;单甲基镓(MMG),0.5。二甲基镓(DMG),0.2;镓0.3; 分子消除的乙烷0.3; 游离甲基1.5。发现了在216和220 nm处的两种新的电子吸收,并暂时归因于DMG *。
