Abstract:
The GaCH3 radical has been directly detected by far UV laser mass spectrometry for the first time, as a UV laser photofragment from gaseous trimethylgallium Ga(CH3)3, but not from triethylgallium, Ga(C2H5)3. The relative yield Y(λ) of GaCH3 was measured, at various UV photolysis laser wavelengths λ=193, 210 and 245 nm, and follows the absorption spectrum of the Ga(CH3)3 precursor molecules.
