Substituents placed on the phenyl rings of 2,3-diphenyl-1,3-thiazolidin-4-one affect the electron density surrounding both the methine proton and the C(2) carbon. These changes are reflected in the differing chemical shifts for these atoms relative to the parent compound. The other carbons in the he
## Abstract ^1^H NMR spectra of a series of 1,2 and 1,3βdiarylimidazolidines are analyzed and correlated with their conformational features. Results were interpreted on the basis of chemical shifts and coupling constants of hydrogen atoms and confirmed by ID nOe difference experiments. 1,3βDiarylim
