摘要：
The protonation and deprotonation equilibria of a set of 4-substituted indoles have been studied spectrophotometrically at 25-degrees-C. Ionization data have been analyzed by the Hammett acidity function and the excess acidity methods. The existence of close relationships between the Hammett's sigma-M constants of the substitutents and the ionization constants for both types of acid-base equilibria is reported.
