Abstract
Tritium separation is indispensable technology tor nuclear fission and fusion reactors. Since multiphoton excitation of halocarbons results in highly selective dissociation of deuterated molecules, this method seems to be applicable to tritium separation. However, IR absorption spectra of tritiated molecules available today are limited to a few simple molecules. For this reason, as a first step, we tried to calculate the fundamental vibration frequencies of twelve tritiated halomethanes according to the Wilson FG matrix method. Of the twelve halomethanes, CTF3 was expected to have the C-F stretching absorption at ~1064 cm−1. Since the wave number is in a tunable region of a CO2 laser, and the overlapping absorptions due to CHF3 and CDF3 are weak, we carried out the IR multiphoton dissociation of this compound.
