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
## Abstract Diβ2βmethylnonylphosphoric acid (HA) as an extractant was investigated for the extraction of divalent metal ions into heptane at an aqueous ionic strength of 0.10βmolβdm^β3^ (NaClO~4~) and at 25βΒ°C. The extraction ability of metal complexes decreased in the order Cd(II) β Mn(II) > Cu(II
