Several nitrogen containing species has been unambiguously identified in the Solar System and in the Interstellar Medium. It is believed that such rich inventory of species is a result of the energetic processing of astrophysical ices during all stages of the protostellar evolution. An intrinsic parameter of matter, the complex refractive index, stores all the "chemical memory" triggered by energetic processing, and therefore might be used to probe ice observations in the infrared. In this study, four N-containing ices have been condensed in ultra-high vacuum chamber and processed by heavy ions (O and Ni) with energies between 0.2 and 15.7 MeV at the Grand Accélérateur National d'Ions Lourds (GANIL), in Caen, France. All chemical changes were monitored in situ by a Infrared Absorption Spectroscopy. The complex refractive index was calculated directly from the absorbance spectrum, by using the Lambert-Beer and Kramers-Kroning relations. The values containing the values will be available in a online database: https://www1.univap.br/gaa/nkabs-database/data.htm. As result, other than the database, it was observed that non-polar ices are more destroyed by sputtering than polar ones. Such destruction and chemical evolution leads to variation in the IR albedo of samples addressed in this paper.
