title: Study of hydrolysis of amido-substituted gamma-butyrolactones by pH-stat titration and ultraviolet spectroscopic analyses.
abstract: pH-Stat titration and ultraviolet absorption spectroscopy have been used to study the rates of ring-opening in a series of gamma-butyrolactones and their analogues. The half-lives for the lactones can be related to Hammett inductive and steric parameters.
