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.

冰的中红外光谱和远红外光谱：光学常数和积分吸光度。

通过中红外光谱（4000至500 cm-1 [2.5-20微米]）的实验室光谱已用于计算各种纯分子冰和混合分子冰的光学常数（n和k）和综合吸收系数（A）。与天体物理学有关。研究的冰是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，H2O，CH3OH和H2O + CH3OH + CO + NH3冰的测量范围已扩展到远红外（500至50 cm-1 [20-200微米]）。
