摘要：

Matrix photoionization and radiolysis of methylene chloride and bromide produced and isolated the CH2X2+ and CH2X2+ ions for spectroscopic and photochemical study. The antisymmetric vibrations observed for the parent ions show unusual isotope shifts, which are explained by spin-orbit interaction of the lowest two electronic states of CFUXt4 formed by removal of halogen nonbonding electrons. The major ultraviolet absorption to an excited electronic state of each ion nicely correlates with photoelectron spectra. The parent ions photodissociated with red-visible light, which is in accord with their limited stability in the gas phase. Ultraviolet photolysis of these matrix samples produced infrared spectra of the isolated CHX2+ ions, CHX2 radicals, and the matrix solvated proton ArnH +. © 1979, American Chemical Society.
