Abstract

Time-resolved decays of fluorescence anisotropy were obtained from frequency-domain measurements of the phase angle difference between the parallel and perpendicular components of the polarized emission and the ratio of the modulated amplitudes. These data were measured at modulation frequencies ranging from 1 to 200 MHz. To demonstrate the general applicability of this method, we describe the resolution of both simple and complex decays of anisotropy. In particular, we resolved single, double, and triple exponential decays of anisotropy and the hindered rotational motions of fluorophores within lipid bilayers. The ease and rapidity with which these results were obtained indicate that frequency-domain measurements are both practical and reliable for the determination of complex decays of anisotropy.
