NMR specrra have been measured of the Li", Na+ and r;' ion pairs of the indenyl carbanion in 1,2\_dimethoxyethane and tetsahydrofuran as a function of temperatzre. The changes of the chemical shifts are explained in terms of the detailed structure of the ion pairs. The results in both solvents stro
