The variation of surface composition with rate of flow of a solution of cholesterol in hydroxypropionitrile was measured by He(I) photoelectron spectroscopy as it flowed down a rod. The Marangoni effect is a likely cause of the phenomena observed.

We have used He(I) photoelectron spectroscopy to measure the percent surface coverage for substances dissolved in hydroxypropionitrile, HO(CH,),CN. The concentration at which 100% surface coverage is achieved, C,,, is an inverse measure of surface activity. Measured values of logI,(Clo,), with C,,
