Abstract
The n.m.r. spectra of cyclobutanone and thietan partially oriented in the nematic phases of liquid crystalline solvents have been obtained. They show that in these solutions cyclobutanone is planar whereas thietan experiences an appreciable ring puckering vibration. An approximate estimate of the mean amplitude of these vibrational modes (10°) has been obtained, the results being in qualitative agreement with microwave studies in the gaseous phase.Keywords
