摘要

Photodissociation of trifluoroethylene (F2CCFH) at 157 nm has been investigated using photofragment translational spectroscopy. Four dissociation channels have been experimentally observed. molecular KF elimination, H atom elimination, F atom elimination, and double bond breaking. Double bond breaking is found to be the most important channel, while molecular HF elimination and H atom elimination are found to be significant. Contribution from F atom elimination is minor. Product translational energy distributions for all dissociation channels have been determined. The translational energy distributions for all four dissociation channels are peaked away from zero energy. This is quite similar to that of 1,1-difuoroethylene. Branching ratios and averaged energy partitions for all dissociation channels have also been estimated. (C) 1998 American Institute of Physics. [S0021-9606(98)01648-1]. [References: 18]
