Abstract

The carbon-isotope selectivity in the multiphoton dissociation of CF3Br is studied in the collisional region of supersonic free jet. The isotopic abundance of12C and13C in C2F6 formed by recombination of the dissociation products is measured with a quadrupole mass spectrometer. An enrichmet factor of 9.4 is obtained for12C with the 9R(30)CO2 laser line while the factor of 6.9 is obtained for13C with the 9P(16) line.
