The structures of trimethylene oxide and trimethylene sulphide as studied by proton magnetic resonance of the solutions in a nematic liquid crystal

Abstract

The structures of trimethylene oxide and sulphide have been studied by the nematic liquid crystal N.M.R. method. Corrections for the ring puckering motion have been applied and structures determined in conjunction with data from microwave spectroscopic studies. Improved results are obtained if a third motional constant is included in the analysis.
