IR transmittance spectra in optical-depth scale (P polarization) of CH3OH:N2 ice (about 250 nm thick) deposited at 16 K before processing (dashed line), after bombardment with 1.36 × 1015 200 keV H+ cm-2 (dose = 36 eV/16u; dotted line), and after photolysis with 2.42 × 1018 photons cm-2 (dose = 41 eV/16u; solid line). HNCO, N2O, OCN, HCN, and CH2N2 are not detected after UV irradiation.
