Laboratory spectra through the mid-infrared (4000 to 500 cm-1 [2.5-20 micrometers]) have been used to calculate the optical constants (n and k) and integrated absorption coefficients (A) for a variety of pure and mixed molecular ices of relevance to astrophysics. The ices studied were H2O, CH3OH, CO2, OCS, CH4, CO2 + CH4, CO2 + OCS, CO + CH4, CO + OCS, O2 + CH4, O2 + OCS, N2 + CH4, N2 + OCS, H2O + CH4, H2O + OCS, and H2O + CH3OH + CO + NH3. In addition, the measurements have been extended through the far-infrared (500 to 50 cm-1 [20-200 micrometers]) for the H2O, CH3OH, and H2O + CH3OH + CO + NH3 ices.
通过中红外（4000至500厘米⁻¹[2.5 - 20微米]）波段的实验室光谱，已用于计算与天体物理学相关的各种纯净和混合分子冰的光学常数（n和k）以及积分吸收系数（A）。所研究的冰包括H₂O、CH₃OH、CO₂、OCS、CH₄、CO₂ + CH₄、CO₂ + OCS、CO + CH₄、CO + OCS、O₂ + CH₄、O₂ + OCS、N₂ + CH₄、N₂ + OCS、H₂O + CH₄、H₂O + OCS以及H₂O + CH₃OH + CO + NH₃。此外，对于H₂O、CH₃OH以及H₂O + CH₃OH + CO + NH₃冰，测量范围已扩展至远红外（500至50厘米⁻¹[20 - 200微米]）。
