Abstract

The PFT ^13^C NMR spectra of some representative 1‐azirines are discussed. Two striking features are the large ^13^C^1^H spin coupling constants and the diagnostic chemical shift of C~3~.

The free acids and sodium salts of a series of sulphonated azobenzene dyestu †s were examined in the solid and solution states by 13C and 15N NMR spectroscopy. In solution the spectra of both the free acids and salts are characteristic of trans-azobenzene structures, as are the spectra of the solid
