The ultra-violet absorption spectra of substituted phenyl amino-1,2,3-triazoles

The ultra-violet absorption spectra of isomeric substituted phenyl amino-1,2,3-triazoles have been studied. The influence of the substituents in the 1-, 4-, and 5-positions is discussed. The spectra of these triazoles have been of significant use for analytical and structural studies in this heterocyclic system.
