Cs+ reactive ion scattering (RIS) and low energy sputtering (LES) techniques were used to examine the surface reaction products, in conjunction with temperature-programmed desorption (TPD) to monitor the desorbing species. The study indicated that the reaction of SO2 with the ice surface occurred through several distinct intermediate states, including a solvated SO2 species, a DSO2 species, and a strongly ionic molecular species, and these intermediates could be isolated on the ice surface due to kinetic trapping. %I ACS Publications
