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.
