Abstract The mean esr linewidth of hfs components of aqueous mangenese salt solutions has been measured a t 9 GHz and room temperature from small to medium concentrations, also with added diamagnetic salts. In all cases the linewidth depends on the viscosity of the solutions. Further, already at very small concentrations a specific anion dependend line broadening has been observed, evidently resulting from ion pair formation. Roughly spoken, in the whole concentration range two anion families exist. Nitrate and halides show smaller line broadening, they form ion pairs with long lifetime. Sulfate, acetate and formiate show larger line broadening; they form ion pairs with short lifetime.
