- Chemistry of the Phenoxathiins and Isosterically Related Heterocycles. XX (1). Assignment of the 13C-NMR Spectra of Phenasazine-10-chloride and Several Substituted Analogs. The Effect of Substitution on the Anisotropic Reorientation of the Phenarsazine System.

The total assignment of the (13)C-nmr spectra of phenarsazine-10-chloride and several substituted analogs is reported.Spin-lattice (T1) relaxation measurements have shown these systems to reorient anisotropically.In the case of the parent system and the 3-chloro substituted system, the axis of anisotropic reorientation has been shown to pass approximately through the center of the molecule.In the case of benzophenarsazine-7-chloride, the axis of anisotropic reorientation, which has been accurately defined, is shifted 23 deg from that in the previous cases, the shift occuring in the direction of the benzo-moiety.
