Intercalation in C60: High resolution 13C NMR results

Solid state high resolution 13C NMR has been used to investigate the physical properties of various phases obtained after intercalation of given chemical species in C60. We present here the case of molecular oxygen, which do not induce charge transfer with the host molecules. We show that, via the magnetic characteristics of the intercalant, information can be gained on its position and movement in the structure. In particular, molecular oxygen is found to occupy the middle of the octahedral site in the fcc structure of solid C60.
