We propose a two-parameter model Hamiltonian to analyze the low-energy dynamics of endohedral C60 fullerene complexes such as Li+@C60, Na+@C60, CO@C60, LiF@C60, and LiH@C60. The simplicity of the model is a direct consequence of very strong constraints imposed by both high symmetry and close confinement conditions, on the spherical anisotropy of the guest-cage interaction. In the parameter space region expanded by the selected systems, the guest low-energy dynamics undergo transitions from almost free rotations to more or less hindered rotations. These dynamics produce very particular features in the low-temperature rotational spectra, which can be taken, therefore, as fingerprints of a particular guest-cage interaction. © 1997 John Wiley & Sons, Inc.
