Selective T/H separation by NH3 laser multiple-photon dissociation of CTCL3

The multiple-photon dissociation (MPD) of CTCL₃ and the selectivity of T/H separation were investigated using a pulsed NH₃ laser, whose radiation contained a few lines depending on operating conditions. When Xe was added to chloroform, the dissociation rate of CTCL₃ increased at chloroform pressures below 2 Torr as a consequence of the removal of multiple-photon absorption bottleneck by collisions with Xe. The dissociation rate of CTCl₃ decreased monotonically with increasing chloroform pressure from 0.2 to 7 Torr. The depletion of CHCl₃ was not observed within experimental errors. The lower limit of the tritium enrichment factor in photo-products produced by one pulse irradiation was 570 at chloroform pressure of 2 Torr.
