✦ Synopsis

Complete layers of some lipids are formed spontaneously on the surfaces of solutions of sufficient concentration in certain solvents, e.g. phosphatidylcholine (egg lecithin) and phosphatidylinositol (wheat germ) dissolved in hydroxypropionitrile. The He(I) photoelectron spectra of phosphatides in such layers contain: (1) a broad band, assigned to alkyl groups, with maximum intensity at about 11 eV, (2) another broad band at about 8 eV, assigned to the PO;group with about 1% of the band area of (1).

It is shown how films of pure or mixed lipids can be investigated by means of He( I) photoelectron spectroscopy; the relationship between the results and those from pressure/area studies is discussed. Films of phosphatidylcholine (egg lecithin), cholesterol and mixtures of the two have been studied,
