Selective ir laser chemistry of CDF3 in natural fluoroform

  • 32 Accesses

  • 11 Citations


Selective decomposition of CDF3 at natural abundance level (≈150ppm) in fluoroform has been achieved by infra-red multiple-photon excitation at moderate substrate pressure using 100 ns FWHM CO2 laser pulses. Effects of energy fluence, number of laser pulses, buffer gas pressure and substrate pressure on decomposition yield and bulk selectivity are reported and discussed.
