Intramolecular Interaction between the Hydroxyl Group and the Oxirane Ring

Abstract
The intramolecular interaction between the hydroxyl group and the oxirane ring has been detected by means of studying the infrared spectra in the 3μ region of various hydroxyalkyloxiranes. The O–H stretching absorptions of several compounds which have limiting structures in the sence of the conformational preference have been closely examined. The results indicate that the intramolecular interaction takes place between the hydroxyl group and the electron orbitals involved in the formation of the C–O bond, while that involving the electrons of the C–C bond can be neglected.
