Because of the high symmetry involved the jahn teller effect is the natural starting point for considering electron phonon or vibronic interactions in icosahedral moleculesthis work is the first comprehensive theoretical analysis of the jahn teller interaction in c60 and other icosahedral complexes the importance of this research derives in part from the increasing widespread interest in . Read free the jahn teller effect in c60 and other icosahedral complexes systems molecules and solids occurs even in nondegenerate electronic states under the influence of sufficiently low lying excited states of appropriate symmetry the pseudo jahn teller effect is the only source of instability and distortions of high. The jahn teller effect is most often encountered in octahedral complexes of the transition metals the phenomenon is very common in six coordinate copperii complexes the d 9 electronic configuration of this ion gives three electrons in the two degenerate e g orbitals leading to a doubly degenerate electronic ground state such complexes distort along one of the molecular fourfold axes . Abstract a model based on a static jahn teller distortion of c 60 is shown to explain the experimentally observed g values of c 60 the results of t 1u h g coupling in which the distortion axis can be in any direction are recounted this static jahn teller coupling explains the axial g tensors that are observed the more common isotropic g tensors are explained in terms of a collection of . In c 60 and other icosahe dral complexes jahn teller effect of c60 monoanion in the first electronically excited states was theoretically investigated the orbital vibronic coupling
