The molecular structures and spectral and luminescent properties of 2,3,7,13,17,18-hexamethyl-8,12-di-nbutylcorrole and 7,13-dimethyl-8,12-di-n-butylcorrole free bases in solutions at 288–328 K were studied using luminescence and absorption spectroscopy and quantum chemistry. Absorption and fluorescence spectra of the compounds were shown to be superimposed spectra of two NH-tautomers. Individual tautomer spectra were identified. Bands were assigned to specific transitions. NH-tautomer equilibria in the ground S₀ and lower excited S₁ singlet states were characterized.
