The spectral shifts of the first absorption bands brought about by cyclic terminal groups in analogues of Michler's Hydrol Blue, Malachite Green, and Crystal Violet are determined mainly by inductive effects.Dye cations containing terminal pyrrolidino substituents are significantly more stable than those possessing piperidino groups as a result of differences in basicity brought about by a change in size of the saturated heterocyclic ring.

Rate constants and the activation parameters ΔH(excit.) and ΔS(excit.) have been determined for the hydrolysis of Pyrrolidine Green over the pH range 10-11.The equilibria associated with the hydrolysis of the dye have been studied over the pH range 0-10 and a reaction scheme is proposed.Equilibrium studies have been extended in the pH range 6.8-7.8 and the thermodynamic parameters ΔH0 and ΔS0 have been obtained.
