— In the course of observing the formation of Schif bases of phosphatidyl ethanolamine and phosphoryl ethanolamine with all‐ trans retinal in a detergent micelle, we have studied their spectroscopic behavior and ORD properties. In so doing, we have demonstrated that all‐rruns retinal itself, although having no intrinsic chirality at the aldehyde group, gives a marked Cotton effect, when dispersed in a CTAB micelle, at the absorption peak of the nπ* transition. This extrinsic chirality is attributed to the markedly asymmetric environment of the Stern layer of the micelle, and its significance is related to the ORD behavior of rod outer segments.
