Abstract:
An experimental investigation was made of multiphoton dissociation of (CF3)3CBr molecules in the field of CO2 laser pulses with the aim of obtaining high concentrations of (CF3)3C radicals. Multiphoton dissociation of (CF3)3CBr could result in successive detachment of the bromine atom and of the CF3 group. Selection of the excitation conditions ensured a high yield of the (CF3)3C radicals and a low yield of the CF3 radicals.
