Abstract :
The fluorescence decay of the linear dye probe DODCI in bilayer membranes is faster in the presence of sucrose in aqueous solution. This is a consequence of the effect of refractive index on the radiative rate of the oriented molecules inside the bilayer. The second-rank order parameter 〈P2(cos θ)〉, determined by the lifetime method, is consistently less than that determined by the anisotropy method. This discrepancy is satisfactorily explained by a bimodal orientational distribution whereas an unimodal distribution is not adequate.
