Sažetak
We have investigated the alkali metal fulleride Na_2CsC_60 by Na-23 nuclear magnetic resonance (NMR). The NMR line of the tetrahedral site is split below 170 K (T and T' lines) similarly to the A(3)C(60) compounds with A = Rb or K. The intensity fraction of the T' line follows the same temperature dependence as the C-13 NMR line width. We have also found that the spectrum is independent of the cooling rate. Spin-echo double resonance measurements show that T and T' sites are mingled on a microscopic scale. We propose that the different Na-23 NMR lines correspond to different fullerene orientational environments of the tetrahedral alkaline site.
