Natnral abundance 13C NMR studies were carried out on a series of phenothiazines, pyridobenzothiazines and phenoxazines. Chemical shift assignments were made on the basis of models, coupling patterns and aromatic substituent effects. For most of the compounds studied, substituents influence only the
