The reflectance of liquids squalane and squalene between 2 and 25 eV have been determined by closed cell double ionization chamber methods. Kramers--Kronig analysis of the data gives optical functions from which are calculated the dielectric functions, energy loss functions, and mean free path for photons and electrons. Values of yield predicted from a theoretical model of photoemission are found to be about 11% at 16 eV declining to 4% at 25 eV. However, no photoemission was observed over this energy range.
