- Description
- NIR spectra of CH3OH:H2O mixtures at 35 and 60 K irradiated with H+ 30 keV.
- Number of spectra
- 7
- Variable type(s)
-
- irradiation dose
- sample composition
- Comments
- We irradiated CH3OH:H2O ices mixtures on the SIDONIE isotope separator at IJCLab (Orsay, France) using H+ ions at 30 keV.Reference spectra were collected on the MgF2 substrat. Spectra are not corrected for interference fringes. Spectra are corrected for athmospheric contribution (CO2 and H2O)
