The photofragment translational spectroscopy with vacuum ultraviolet ionization was used to investigate the photodissociation of 1,2 dibromo-tetrafluoroethane (Halon-2402) at 193 nm. The state-selected translational spectroscopy with resonance-enhanced multiphoton ionization was used to investigate the photodissociation of the compound at 193, 233, and 266 nm. The ultraviolet photodissociation was further studied by determining the product branch ratios, angular distributions, and translational energy distributions. A model was proposed to describe the wavelength-dependent bromine quantum yield. The implications of these products in upper atmosphere were studied.
