The rotational dynamics can be explained in terms of the Stokes{\frac{ }{ }}Einstein{\frac{ }{ }}Debye hydrodynamics theory under stick boundary condition by considering the rotating body as a prolate spheroid enclosing the complex. This overestimates the intrinsic molecular volume by a factor of 1.5. The difference can be accounted for by solvent molecules intercalated in the interligand space and stabilized by electrostatic interaction with the charge of the metal atom.}}, year = {1994} }
