Abstract
The Compton profiles of MoKa x rays inelastically scattered from three liquids of molecular formula C4H8O2 (dioxane, n‐butyric and isobutyric acids) are compared with one another and with theoretical profiles computed from localized molecular orbital wavefunctions. The three experimental profiles are found to be not significantly different from one another, in agreement with the theoretical model, but they differ slightly from the theoretical profiles.
