Abstract:	The UV absorption spectrum of trimethylsilyl radical was observed at 256 nm for the first time by photolysing allyltrimethylsilane and hexamethyldisilane with an ArF excimer laser. A bimolecular rate constant for recombination of trimethylsilyl radical of (2.5±0.5×10⁻¹¹ molecule⁻¹ cm³ s⁻¹ was measured.
