Abstract
By means of pulsed Nuclear Magnetic Resonance and Magic Angle Spinning we have studied crystalline C60 x 0.2 C70 x 1.5(CHCl3). We present da ta of the spin lattice relaxation (T1) of C-13 nuclei as a function of temperature between 140 and 310 K. Their analysis has been made in te rms of the chemical shift anisotropy model. Our results show that the high temperature free rotation of C60 molecules is not suppressed and that there is no structural phase transition near 260 K as observed in pure crystals of C60.
