It has recently been suggested [ll that when l,l,l-trichloroethane is irradiated with a continuous-wave COP laser in the presence of SF6 sensitizer, the decomposition occurs in a molecular manner, viz. CH3CC13 4 CHZ = CCl2 + HC1 rather than by a radical-chain mechanism CHBCC13 CH3 -CC12 + C1 C1 + CH
UFs undergoes decomposition m the presence of SF6 when mixtures of both are madiated wrth a TEA CO2 laser. The mechanism for UFe decomposition may involve vrbrational energy transfer from excited SF, and laser absorption from the same laser pulse by excited UFe in its vibrational quasi-continuum \*
