Kwiatkowski, J. S. published the artcile< Electronic structure and spectra of organic molecules. XVI. Amine-imine tautomerism in azines substituted by amino groups>, Application of C4H5N3, the main research area is tautomerism aminoazine electronic structure; azine tautomerism electronic structure; iminoazine electronic transition energy; pyridine tautomerism electronic structure; diazine tautomerism electronic structure.
For both amine and imine tautomers of amine-substituted pyridines and diazines, Pariser-Parr-Pople type calculations (K., 1970) gave singlet-singlet transition energies which agreed with exptl. data. In all cases, the singlet-singlet transitions of the imine forms red shifted relative to the corresponding transitions of the amine forms.
Acta Physica Polonica, A published new progress about Tautomers. 20744-39-2 belongs to class pyridazine, and the molecular formula is C4H5N3, Application of C4H5N3.
