| Abstract: | Isotope separation of tritium from deuterium in heavy water was attempted by CO2-laser-induced, highly-selective multiphoton dissociation of C2TF5 present in C2DF5. Single-step T/D separation factors exceeding 3000, 1000, and 500 were attained, respectively, for the first time with CO2 laser 10P(34) 931.0 cm?1 at 10, 20, and 30 Torr pentafluoroethane pressures at ?78 °C (i.e., equivalent to 15, 30, and 45 Torr at room temperature). |
