Photolysis of CF3CI with a 9.6 pm CO2 laser has indicated that carbon-13 selectsvrty increases when the excitation frequency is sliihtly red-shifted from the ~1 band centreat R(18). A selectmrty enhancement with substrate pressure was aiso observed if the P(l8) line, which is far red-shifted, is use
We have compared the performance of CF31, CD31, and CH31 in an atomic iodine photodissoctition laser over the pressure range l-200 torr. At pressures below 5 torr, CD31 produces larger energy outputs, while above 5 torr CFJl gives supcrior performance. The crossing of the laser cnergf output versus
