Kinetics of partly diffusion controlled reactions. VII — Pyrene excimer formation in erythrocyte membranes

Intermolecular excimer forming systems such as pyrene have been proposed as probes for the microviscosity measurement of model and biological membranes. However, our experimental study of pyrene excimer formation in erythrocyte membranes and the theoretical calculations show that it is quite difficult to get the diffusion coefficient of pyrene in membranes and therefore the microviscosity of its environment.
