Cesium-133 chemical shifts were measured in a number of solvents as a function of salt concentration and of the counterion. Infinite-dilution chemical shifts (vs. aqueous Cs/sup +/ ion at infinite dilution) ranged from +59.8 ppM for nitromethane solutions to -29.4 ppM for pyridine. In general, the magnitude of the downfield chemical shift reflected the donor ability of the solvents. Ion-pair formation constants were calculated from the concentration dependences of /sup 133/Cs chemical shifts in several nonaqueous solvents. (2 tables, 7 figs, 22 refs.)
