Thin film transmission infrared spectra and a list of integrated absorbance values (band strengths) of bands in the 2.5 to 20 micron range of various molecular solids deposited on a CsI window cooled to 10K are presented. These solids include molecules known or suspected to be present on interstellar grains such as H2O, CO, NH3 and CH4 and mixtures of these molecules as well as various hydrocarbons. The method is described by which the absorbance values derived can be used to estimate column densities of species absorbed on interstellar grains and other solids associated with celestial IR sources.
