XVII.Investigation of thin films of organic substances by electron diffraction

Abstract

The method of electron diffraction was used to investigate a type of pattern obtained with films of certain “grease-like” mixtures spread on various types of backing. This pattern indicates orientation of the molecules normal to the surface of the film, and experiment shows that this orientation is present both at the vacuum-grease and “backing-grease” interfaces. A substance which gives this pattern is likely to act well as a lubricant.
