The UV absorption spectrum of trimethylstlyl 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)X10-" molecule-' cm3 s-' was measu
Two transient absorptions have been detected in the infrared region during the gas-phase photolysis of azoisobutane/O:! mhtures nt 293 K. These transitions centred at 693.7 i 0.5 cm-' and 760 f 2 cm-' are assiged to the I-butylperoxy radical. A simple flow system at atmospheric piessure was used tog
