A conformational analysis for meso- and d,l-2,3-difluorobutanes has been carried out, employing 1H and 19F NMR and theoretical calculations.The real configurations of the two isomers were assigned by specific optical rotation measurements of the products coming from an optically active precursor.Gauche conformations were predominant for meso (E) isomer, while the d,l (T) isomer showed all possible staggered rotamers almost equally populated.Finally remarks for NMR peak assignment of homo- and copolymers partially fluorinated by using gauche additive effects are given.
