Generation of (CF3)3C radicals by infrared multiphoton dissociation of the (CF3)3CBr molecule

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.
