摘要：
Photopolymerisation and photoinduced diffusion of the molecular oxygen in oxygen bearing C-60 films by lambda=459, 514 nm continious laser radiation and by 100 - fs, lambda=395, 410 nm pulses were compared by visual observation of photodarkening spots and by recording the Raman spectra, in the range 200 - 1700 cm(-1) of the irradiated regions. It was found out that in the case of femtosecond pulses, the efficiencies of both photoinduced processes are significantly lower than those in the case of continious radiation.
