Abstract
13 C N.m.r. spectra of trans-azobenzene and a series of its substituted derivatives have been obtained in the solid phase. Additional effects are observed, not present in the solution spectra of the species, and these are shown to be due to the locking of the molecules into particular conformations in the solid. The first 13C n.m.r. spectrum of a reasonably complex solid dyestuff is shown and an assignment of this has been attempted, based upon the effects observed in the solid reference compounds.
