DFT-derived binding energy distributions for methanol and photolysis products on ASW ice, integrated into astrochemical models, demonstrate sensitivity of radical abundances to BE calculation methods.
The CH₃OH/CH₃CN ratio in the S68N outflow is constant at ~100-200 and matches gas-phase astrochemical models only when cosmic-ray ionization rates are raised to ~10^{-14} s^{-1}.
