The rotational diffusion of diphenylhexatriene (DPH) determines its fluorescence depolarization. Time-resolved polarization measurements were used to calculate the coefficient of diffusion of this probe in human crythrocyte ghost membranes on the basis of a diffusion theory of limited rotation. The diffusion coefficient is 5.9 × 107sec−1at 37°C; this was compared with the diffusion coefficient of DPH in liquid paraffin for an estimation of the microviscosity of the membrane bilayer.
