Paper Abstract

The slow rotational diffusion of macromolecules has been investigated by measuring the decay of dichroism in laser-pulse induced transient emissions for triplet probes bound to the molecules. A comparison of the anisotropy parameters of phosphorescence and delayed fluorescence from eosin-bound bovine serum albumin (BSA) is described. The results indicate that the measurement of delayed fluorescence is often the preferable option for investigating the rotational diffusion of the macromolecules.
