Abstract
A new quantitative approach, based on the analysis of overlapping band s, in determining the tautomeric equilibrium constant and the individu al spectral curves of the pure tautomeric forms of 1-phenylazo-4-napht hol and its derivatives is applied. The influence of some important fa ctors affecting the tautomeric equilibrium, such as solvent polarity, substituents in the phenyl ring, etc., is evaluated.
