The long-standing question of the nature of the low-energy transition present in the optical spectrum of azo dyes was addressed by investigating the resonance Raman spectrum of 4-(2-pyridylazo)resorcinol (PAR). The Raman spectra were obtained at di β erent pH values where the prevailing species are t
