Dye laser probing of primary C2 radicals formed by IR intense field photolysis of ethylene

  • 38 Accesses

  • 34 Citations


The C2-radicals in the lower electronic statea 3 II u have been studied by the method of laser-excited luminescence of products of ethylene IR photolysis. The dependence of C2-radical concentration on IR field power density and its time evolution have been investigated. The threshold characteristics of C2-radical occurrence and the ratio between excited and unexcited radicals have been determined. Different mechanisms for their formation are being discussed.
