Abstract

The pulsed InfraRed (IR) photodissociation of pure CF3Br and a 1:3 mixture with H2 has been studied as a function of pressure, temperature, fluence and wavelength. The results have been obtained by mass spectrometry. Maximum enrichment for carbon 13 is obtained when irradiating with the 1046.9 cm−1 (9P20) line, but the selectivity is stronger at longer wavelengths. The enrichment factor tends towards 1 when pressure increases with the pure substance, but it is less affected in the mixture. It seems that hydrogen has a buffer effect. The selectivity shows maxima for all lines with the fluence and increases when the temperature is decreased from 22 to − 85°C. Some enrichment is observed for the bromine 79 isotope when irradiating with 1046.9 cm−1 (9P20).
