Pickoff-annihilation parameters, interpreted in terms of the free volume model, are shown to be indicators of changes in overall protein conformation due to environmental perturbations such as temperature and pH. Measurements are discussed for both thermally stable and unstable proteins as well as inhibited enzyme.
