This dataset includes the infrared (IR) spectra before and after 2 keV electron irradiation of ice samples containing CO, 15N2, and H2 molecules corresponding to Experiments 1-6 described in the paper entitled "Organic chemistry in the H2-bearing, CO-rich interstellar ice layer at temperatures relevant to dense cloud interiors". In addition, the gas-phase data collected by the quadrupole mass spectrometer (QMS) during the temperature programmed desorption or TPD (corresponding to the signal of selected m/z fragments), as well as the ice sample temperature during the TPD are also included for each experiment.
