From the theory of chemical shifts, substituent-induced ring proton shifts should depend primarily on the n-electron charge density of the carbon atom to which the proton is bound assuming substituent-independence of the ring current effect and minimal long range substituent effects for meta and par

In the course of the chemical study of episulfoxides (I, 2), we hove found in the PMR spectm of ethylene episulfoxide (I)\*3 and propylene episulfoxide (II) that the J-values between ring protons are abnormal in comparison with those obtained in other three-membered heterocyclic compounds.
