Proton Magnetic Resonance, Structure and Stereoisomerism in Cyclic Sulfites BY J. G. PRITCHARD AKD P. C. LAUTERBUR RECEIVED OCTOBER 3, 1960 The proton magnetic resonance spectra and structure of eth? lene sulfite, ethylene sulfate, isobutylene sulfite and the two stable, geometrically isomeric species of propylene sulfite are discussed The isomerism in the propylene sulfite system is demonstrated for the first time; the isomers are characterized ut
