Abstract
Recently, the dipole moments of the six isomeric trans-1,2-dipyridylethylenes (DPE) have been reported1• With the exception of 1,2-di-(pyridyl-4)-ethylene (4,4-DPE) all isomers can exist in several configurations depending on the relative
position of the two nitrogen atoms. Thus, for the six trans-isomers, 15
non-identical configurations are possible2 (Fig. 1). In the determination and discussion of the observed dipole moment, the knowledge of the amount of each configuration present in the measured sample is of great importance. Two procedures have so far been used to obtain this information.
