Abstract

Infrared optical constants of ices allow us reproducing astrophysical observations of absorption, reflection or extinction infrared spectra of these species. They are also needed as input in some astrophysical models. Infrared band strengths provide a direct tool to quantify the composition of ices in astrophysical media. In this chapter we describe different experimental ways to obtain these magnitudes. They are based on infrared transmission absorption spectra of ice layers grown on infrared transparent substrates. The main approximations implicit in the procedures are reviewed.
