The enrichment factor of carbon-13 m the products of multiphoton dissociation of CzFsCl has been investigated asa function of CO&xer wavelength and fluence. Pressure effects have been studied both on the pure sample and in the presence of several additives (He, Xe, 02. Hz. NO, 12). Dissociation of 1

β¦ Synopsis
It is shown in experiments on CF3B-r that rotational relaxation may either increase or decrease the value of mu&Photon dissociation selectivity, The mechanism of the influence of rotational relaxation on selective dissociation is analyzed.
