Rate const. for the reactions of radicals with NO, NO2, O2, C2H4, 2-butene, benzene, toluene and CCl4 have been detd. using a combined laser photolysis/laser absorption technique. Ph radicals were generated by 248 nm excimer laser photolysis of C6H5X, where X = Cl, Br and NO. Their temporal behavior was monitored using cw-laser line absorption in the ~X2A1 - ~A2B1 transition at 488 nm. At this wavelength the absorption cross section of Ph has been detd. as (9 +- 4) 10-19 cm2.
