Halogenated hydrocarbons are important due to their ability to destroy ozone and act as greenhouse gases. In order to investigate the degradation reaction pathways for halogenated compounds, a model molecule, CD3CD2CHFBr, was prepared using the chemical activation technique. The activated CD3CD2CHFBr was prepared by combination of CD3CD2 and CHFBr radicals prepared by photosensitizing CD3CD2I and CHFBr2, respectively using Hg(3P0). The unimolecular decomposition pathways for CD3CD2CHFBr are still being analyzed. However, it was found that the E/Z ratio for the products of the decomposition changes with pressure. This may be due to an E/Z isomer shift caused by secondary mercury photolysis. It was also found that the 1,2-DBr elimination reaction leads to the prevalent product formed at all pressures analyzed.
