Summary

We have measured the ultraviolet absorption spectra of CFCl3 and NO2 physically adsorbed on lithium fluoride (LiF). The technique employed was photoacoustic spectroscopy, which is sensitive to small amounts of material adsorbed on powdered solids. Preliminary results indicate that the optical absorption band of CFCl3 is broadened by contact with the solid LiF. Broadening of this kind may be responsible for reported long-wavelength photolysis of these molecules on transparent solids. Broadening of the NO2 absorption band was not seen on LiF.
