Abstract

Lithium‐7 and lithium‐6 spectra were obtained for four solid air‐sensitive complexes of LiBH~4~ under both magic angle spinning (MAS) and static conditions. The MAS experiments were carried out using a specially designed rotor insert to prevent degradation of the sample. The spectra yield semi‐quantitative information about the magnitude of the quadrupolar coupling constants, but some structure in the static spectra cannot be fully explained. Chemical shift variations are, as expected, modest. Only a single MAS centreband is seen in each case, suggesting that there is only one lithium atom in the asymmetric unit.
