| Abstract: | The enrichment factor of carbon-13 in the products of multiphoton dissociation of C2F5Cl has been investigated as a function of CO2-laser wavelength and fluence. Pressure effects have been studied both on the pure sample and in the presence of several additives (He, Xe, O2, H2, NO, I2). Dissociation of 12C2F5Cl and enrichment in carbon-13 are strongly affected by O2, which reacts with the fluoroalkyl radicals formed in the dissociation process. |
