It has been shown through observations in the infrared from ISO (Infrared Space Observatory) and SST (Spitzer Space Telescope), the existence of astrophysical ices toward protostars. Among them, there are H2O, CO, CO2, NH3, CH3OH, CH4, HCOOH, H2CO, CH3CHO. In the same time of observations, several papers were published, showing the formation of complex molecules from simple one, through energetic processing with photons and particles, mimicking the typical scenario in the star-forming regions.Here we will employ data of astrophysical ices obtained from laboratory in the infrared into computational models (RADMC-3D, ProDiMo), that calculates radiative transfer in attempt to better simulate the astrophysical environments around young stellar objects in a more realistic approach. The experimental data will be measured, in principle, at two laboratories: LASA Lab. at Univap (UV, soft X-rays and electrons) and Ganil Lab. at France (energetic ions). By using this methodology, we will simulate the physical observers from telescopes in the infrared, such as spectra and images. Such study allow us calculate the complex refractive indces of several molecules, as well as understand the influence of radiation under the band strength, which is fundamental parameter to estimate the abundances of molecules in the solid phase. Additionally, will be investigated if the complex molecules itself is a product of the stellar radiation field, given the scenario of class I and T-Tauri objects, instead the chemical processing of the ices in the primitive cloud.
