A Quantum-Chemical and Correlation Study of the Ionization of Purpurin
Russian Journal of General Chemistry, 2005 Anthraquinoid tautomers participate in the ionization of purpurin. The tautomerism takes place in both ground and excited states of the molecules; the excited state is more sensitive to the tautomerism. The solvation and ionization shift the tautomeric equilibria.
