Since the 1970s, attention has been focused on the effects of these compounds on the destruction of ozone in the stratosphere and on global warming. Takahashi and coworkers detected ClO radicals and measured the product branching ratios of the title reaction system via the technique of vacuum ultraviolet laser-induced fluorescence. Yu and coworkers studied the mechanisms of the title reaction induced by the photolysis of the CF3Cl-O3 system at 253.7 nm.展开更多
