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

The resonance-enhanced multiphoton ionization (REMPI) of the OH radical in the gas phase was studied using an isothermal discharge-flow reactor for the production of OH radicals (H+NO,+OH+NO), tunable laser light from an excimer-pumpeddye laser, and a time-of-flight (TOF) mass spectrometer. A mass-r
