Gas-phase photolysis of trimethoxysilane, achieved for the first time by focused ArF laser radiation at 193 nm, yields C-1,C-2 hydrocarbons, methanol and carbon monoxide along with ultrafine nanostructured silicone powder possessing -SiO3 and SiO4 configurations and Si-H and Si-OCH3 bonds. The photolytic process, resulting in efficient removal of the methyl groups, is explained as a multitude of steps involving cleavages of all the available bonds.
