P. Lauginie et J. Conard, PUZZLING FACTS IN ALKALI GIC, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 244, 1994, pp. 19-24
Some Alkali-GIC puzzling features, which may be of more general intere
st (specially to fullerides and conducting polymers) are discussed, na
mely : the validity of charge transfer heterogeneity deduced from NMR
shifts; carbon-alkali hybridization in stage I viewed from 13-C shifts
and relaxation rate; evidence of carbon sigma-pi hybridization in G.I
.C.; possible long-range effects of inserted alkali atoms.
