摘要：

Vapour phase infrared spectra of monomeric trimethylaluminium and its perdeuterated isotopomer have been obtained for the first time, using a novel laser heating technique. Assignment of these spectra was carried out with the aid of ab initio and normal coordinate calculations. Comparison of the spectra with the previously reported matrix isolated spectrum suggests that the free rotation of the methyl groups takes place in the vapour, but not in the matrix. Comparison with the spectra of normal and predeuterated trimethylgallium allows a rationalization of the mechanisms of pyrolysis of the two species.
