## Abstract The ^1^H and ^13^C NMR spectra of partially oriented thietane have been recorded and analysed. The molecular structure was determined assuming the molecule to be planar and rigid. Because of the unsatisfactory fit of the dipolar coupling constants, a model which also takes into account
The \*H, '% and 31P NMR data of several Z-R-2-thiono-1,3-dioxa organophosphorus molecules with 7-membered rings [R = 43, OC6H,, C,H,, CH3, N(CH,),] are reported. The conformation of the 7-membered ring is discussed by reference to the 'J(P0CH) coupling constants which are compared with those observe
## Abstract Cyclodipeptides containing L‐Thr and L‐His residues have been studied by ^1^H NMR in D~2~O and DMSO‐__d__~6~. In the neutral form in D~2~O as in DMSO‐__d__~6~, the folded form of the L‐His residue is not unique. The diketopiperazine ring seems to be not strictly planar.
## Abstract The solution conformation of L‐6‐methylperhydroimidazo[1,5‐c]thiazole‐5,7‐dione (γ‐thiaprolinehydantoin) has been determined from an extensive ^1^H and ^13^C NMR study, allowing the extraction of vicinal inter‐proton and carbon‐hydrogen coupling constants. The major conformation of the
