Light‐scattering changes were found to accompany the bacteriorhodopsin photocycle in a suspension of purple membranes. A light‐scattering signal comprises three phases, connected with (i) bR → M transition, (ii) transition of M to P intermediate (other names: N,R350 intermediate), (iii) P → bR transition. Light‐scattering changes seem to result from changes in the purple membrane shape in response to the bacteriorhodopsin conformational changes during the photocycle.
