The photochemistry of trifluoronitrosomethane adsorbed onto inert gas overlayers was investigated using infrared spectroscopy. Fourier Transform IR spectra of CF3NO adsorbed onto argon, krypton, and xenon at temperatures ranging from 13.5 K to 80 K and high vacuum conditions, 7.5x 10-7 Torr to 6.0x 10-6 Torr were taken. The system was subjected to laser irradiation, diode and helium-neon lasers, over various temperature increments. Analysis of the spectra indicate the formation of the photodimer, (CF3)2NONO, as witnessed by Haszeldine and Mattinson and characterized by Mason. Furthermore, the temperature dependence of the quantum efficiency indicates that geminate recombination and surface translation, followed by dimer formation, are occurring on the surface.
