Light-induced electric fast photosignals from rod outer segment membranes oriented on cellulose filters were measured. The influence of pH and the ionic strength of the aqueous medium on the R2-generating process was investigated. There evidently is a charge displacement within the hydrophobic part of rhodopsin which has an amplitude of .apprx. 2 e.ANG. and which is not connected to the light-induced proton uptake occurring on the same time scale. A proton transfer model is presented which accounts for the observed charge displacements as well as the properties of the spectroscopically defined intermediates.
