13 C NMR spectra of the solid phase have been obtained for biphenyl and a series of its substituted derivatives. Some species give essentially similar spectra in the solid and solution phases, whereas others show clear differences. In several cases the differences are shown to be due to the locking of the molecules into a particular conformation in the solid. For some compounds different chemical shifts for the C‐1 and C‐1′; carbon atoms in the solid and solution phases are believed to reflect differences in the angle between the ring planes in the two phases.
