Resumé

The paper presents the first NMR investigations of a molecular crystalline material CG,(ferrocene),, which consists of two highly rotational mobile molecules. The possibility of charge transfer between ferrocene and C-60 is studied. Experimental results on T-1, T-1 rho and CP relaxation. are presented and compared with the purr ferrocene and C-60. The results were analysed in terms of molecular spectral density function and the amplitude of dipole-dipole interactions. It was found that cross-polarization processes in the investigated samples cannot be described based on the CP fast-correlation assumption.
