TLDR
The correct master equation has five exponential decay terms, with preexponential factors that depend upon the diffusion constants and, in a completely symmetrical fashion, upon the orientations of absorbing and emitting dipoles.
Abstract
Reexamination of the theory of fluorescence time dependence owing to rotational diffusion of rigid macromolecules reveals deficiencies or hidden restrictions in each of the previous treatments. The correct master equation has five exponential decay terms, with preexponential factors that depend upon the diffusion constants and, in a completely symmetrical fashion, upon the orientations of absorbing and emitting dipoles.

Hydration of Proteins and Polypeptides

TL;DR: The chapter presents several proposals for predicting protein hydration based on the amino acid composition of the protein; however, the two main questions concerned include—whether ionic groups are more hydrated than other polar groups, and whether the amide and peptide functions are hydrated or not.

A theory of fluorescence polarization decay in membranes.

TL;DR: The theory is useful for the analysis of fluorescence polarization decay in any system where the orientation of fluorophore is restricted by the surrounding structure.

Hydrodynamic properties of complex, rigid, biological macromolecules: theory and applications.

TL;DR: In this paper, the translational and rotational brownian dynamics of dissolved macromolecules were analyzed using quasielastic light scattering, transient electric birefringence and fluorescence anisotropy decay.
