## Abstract The hydroxyl proton chemical shifts of β‐dicarbonyl compounds involving various β‐substituents have been studied. An additive influence of β‐substituents on the δ~OH~ shift values has been found. The results obtained suggested the existence of only one potential proton energy minimum in
