	abstract = {Peroxides are ubiquitous in the atmosphere and their photochemistry at ice surfaces is important. Here the primary steps following photoexcitation of methyl hydroperoxide (MHP) on ice particles are investigated using the MNDO method that describes semiempirically multiple electronic states and treats non-adiabatic dynamical transitions between them by surface hopping. Results are compared with the isolated MHP. Important findings are as follows. (1) Ice catalyzes the deactivation of MHP from the excited state to the ground state. (2) The deactivation process takes place on a femtosecond timescale and is followed by dissociation into fragments. (3) Recombination of fragments occurs to a small extent on ice, but not for the isolated peroxide.},
