Description
Mid-IR spectra of methanol ice, at 45 K, increasing irradiation doses: unirradiated and irradiated by $H^+$ ions at 30 keV and a total fluence of $1.10^{16} ions.cm{-2}$.

Comments
We irradiated methanol ice on the SIDONIE isotope separator at IJCLab (Orsay, France) using $H^+$ ions at 30 keV and a total fluence of $1.10^{16}$ $ions.cm^{-2}$. Reference spectra were collected on the MgF2 substrat. Spectra are corrected for athmospheric contribution (CO2 and H2O).
