| 摘 要： | The rotation dynamics of C60 molecules in organic superconductor K3C60 has been investigated from the viewpoint of intramolecular interaction.It is determined that the rotation of C60 at room temperature has been frozen up within a small region of rotation angle (0→50°),and pointed out that the reason for the freeze is the physical interaction rather than the geometrical hindrance.The computations of the interactions for alkali-doped compounds A3-xAxC60(x=1,2,3;A,A'= K,Rb,Cs) other than K3C60 have also been carried out.From the obtained results,it is seen that the superconducting transition temperatures Tc are strongly connected with the interactions in them,and this observation is consistent with the discovery of the correlation between Tc and lattice constants a
