Lidocaine forms expanded-type liquid surface films on solutions. The characteristic He(I) photoelectron spectrum of the initial film changes after formation, revealing a change of surface structure. Lidocaine slowly penetrates and replaces a monolayer of egg lecithin.

โฆ Synopsis
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.

By means of He(I) photoelectron spectroscopy, the surface compositions of mixed solutions of sodium oleate and dimethyldioctadecylammonium bromide in hydroxypropionitrile solution have been measured.
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,,
