The influence of inertial effects on the fluorescence anisotropy r is discussed.
From recent work on the anisotropy of a prolate fluorescent molecule in a liquid solvent it is known that its estimated experimental moment of inertia is as much as about 3 orders of magnitude greater than that calculated from its geometry.
In this paper, by using a non-exponential form of the memory function K (t) in the generalized relaxation equation for r (t), a satisfactory agreement between measured and calculated moments of inertia is obtained.
