Isotopically selective dissociation of COCl2 molecules under the action of NH3 laser radiation

An experimental study was made of the yield and selectivity of dissociation of COCl₂ molecules by NH₃ laser radiation pulses of ~ 4 μs duration.The dissociation was found to involve competition between radiative and collisional activation of molecules and the dissociation yield was determined by the latter activation process.
