Abstract
The high-resolution N.M.R. spectra of ten tricyclic heterocycles related to phenothiazine in which the heteroatoms are combinations of O, N, S, Se, Te, and As are reported. The coupling constants are discussed in terms of substituent effects for the heteroatoms. Long- range coupling of the NH and solvent effects are used to make assignments of the protons.Keywords
