Bromine monochloride has been thought to play an important role in surface ozone depletion at polar sunrise recently. The photoelectron spectroscopy (PES) of BrCl is reported. Research shows that the first adiabatic and vertical ionization potential of bromine monochloride are 10.95 eV and 11 00 eV, respectively. The removal of an electron from the highest occupied orbital (HOMO) of bromine monochloride leads to obvious spin orbit coupling peaks which exhibit fine vibrational structure. The analysis of vibrational frequencies shows that the HOMO has a slightly antibonding character. Comparison of different calculations indicates that the Outer Valence Green's Function (OVGF) method gives extremely good results in the calculation of ionization potential, which is in excellent accordance with the experimental values, especially the first vertical ionization potential (10 988 eV).

Key words: photoelectron spectroscopy, bromine monochloride, ionization potential, outer valence green’s function(OVGF)
