Photoabsorption and fluorescence excitation spectra of CHBr2Cl and CHBrCl2 trihalomethanes were measured in the 106-200 nm region using synchrotron radiation as a light source.Main photoabsorption bands observed are assigned as the Rydberg transitions of the outer shell orbitals.In the photoexcitation of CHBr2Cl a diffuse emission band of CHCl(<*>1A''--> <*>1A') was observed in the 500-800 nm region.The radiative lifetime of the CHCl(<*>1A'') state was first determined to be 7.01+/-0.25 μs.In the photolysis of CHBrCl2 at 121.6 nm, the formation of CHCl(<*>1A'') and CCl2(<*>1B1)radicals were observed.The fluorescence thresholds for CHBr2Cl and CHBrCl2 start at 162 and 159 nm with the maximum yields of 5percent and 11percent at 122 and 119 nm, respectively.
