## Abstract The reaction of hot hydrogen atoms originating from 253.7โ and 228.8โnm photolyses of hydrogen sulfide with 1โbutene was investigated. Of the hydrogen atoms undergoing addition a substantial part undergoes it in a first collision (37 and 48% at 253.7 and 228.8 nm, respectively) yielding

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 ultraviolet absorption spectrum of the chloroethylperoxy radical, CH2ClCH202, and the kinetics of its self-reaction have been studied in the gas phase using a flash photolysis technique. The room temperature absorption cross section at 250 nm was determined to be bc~~ac~,o~ ( 250nm) = ( 3.64 5 0
The magnetic circular dichroism of ethylene gas was measured in the spectral region 200-150 nm. A new electronic transit?Jll is observed to underlie the maximum of the N -f V transition. This electronic transition is tentatively assigned as a 7r -Zpo excitation.
Ozonolysis of cis-and trans-2-butene isomers were carried out in a 570 l spherical glass vessel in 730 torr synthetic air at 295 ฯฎ 3 K. The initial concentrations were 5 to 10 ppmv for the isomers and 2 to 5 ppmv for ozone. Quantitative yields were determined by FTIR spectroscopy for CH 3 CHO, HCHO,
