title: Light-scattering studies of the monomer-dimer states of gramicidin A.
abstract: Measurements of the intensity and autocorrelation function of ligh quasielastically scattered by gramicidin A indicate that the molecules exist as dimers in methanol and dioxane and monomers in dimethyl sulfoxide when solute concentrations range from 18 to 50 mg/ml. This gives further evidence that gramicidin A can dimerize in low-polarity media such as the hydrocarbon part of the membrane bilayers.
