    • Abstract

       

      The apparent electric dipole moments ofo-hydroxy biphenyl,o-methoxy biphenyl andpp′-dihydroxy biphenyl have been determined. The values serve to point to the following structural features: (1) Ino-hydroxy biphenyl the two benzene rings seem to be orthogonal and there seems to be an interaction between the proton of the —OH group and theπ-electrons of the unsubstituted benzene ring. (2) Ino-methoxy biphenyl the two benzene rings seem to be slightly tilted from the coplanar conformation. (3) Inpp′-dihydroxy biphenyl the two benzene rings seem to be coplanar.
