The vibrational circular dichroism (VCD) and absorption spectra of gramicidin D in three model membranes (dioctadecyldimethylammonium chloride vesicles, dimyristoyl‐phosphatidylcholine vesicles, and sodium dodecyl sulfate micelles) are presented. The absorption and VCD spectra suggest that the stable gramicidin D conformation in the model membranes is different from those in organic solvents. The presence of cations does not change the membrane‐bound conformation of gramicidin D. © 2001 John Wiley & Sons, Inc. Biopolymers (Biospectroscopy) 62: 336–340, 2001
