We report on the measurements of the 13 C NMR lineshape in the organic ferromagnet TDAE-C 60 between room temperature and 4 K as well as on a simulation of the lineshape in this temperature interval. It is shown that the sudden increase in the inhomogeneous 13 C NMR linewidth in the middle of the ferromagnetic phase can be explained by the freeze out of the pseudorotations of the axes of the Jahn-Teller distortions of the C 60- ions. The correlation times for the Jahn-Teller dynamics of the C 60- ions have been extracted from a comparison of experimental and simulated 13 C NMR lineshapes. A strong correlation between spin ordering and orbital ordering has been found.
