    Description / Table of Contents: The meso or threo configuration of diastereoisomeric molecules is elucidated on the basis of respective NMR spectra of either isomers. The symmetry relationship (according to Raban and Mislow) between protons or groups are not identical in each isomer, and the consequent differences in chemical shifts and spin-coupling constants permit assignment of configurations.
    Notes: La configuration meso ou thréo de molécules diastéréoisomères est déterminée à partir des spectres RMN respectifs xde chaque isomère. Les relations de symétrie (Raban et Mislow), qui existent entre protons ou groupes de ces molécules sont différentes par chaque diastéréoisomère d'un couple donné et ces différences se traduisent dans les déplacements chimiques et constantes de couplage mis en jeu. Des attributions de configuration sont ainsi rendues possibles.
