The NMR chemical shift and line width were measured for /sup 23/Na/sup -/ in tetrahydrofuran (THF), ethylamine (EA), and methylamine (MA), for /sup 87/Rb/sup -/ in THF and EA, and for /sup 133/Cs/sup -/ in THF. In all cases, the counterion was the 2,2,2 cryptate complex of the corresponding cation. The chemical shift of Na/sup -/ is, within experimental error, the same as that calculated for the gaseous anion (based upon the measured value for the gaseous atom) and is independent of solvent. Comparison with the solvent-dependent chemical shift of Na/sup +/ provides conclusive evidence that Na/sup -/ is a ''genuine'' anion with two electrons in a 3s orbital which shield the 2p electrons from the influence of the solvent.
