Proton magnet i c resonance s pect ra of the cha rge trans fer complex. 1-ethyl-4-carbomethoxy pyridinium iodide were recorded in a number of solvents. It was found that 0 (2,6) - 0 (3.5) correlated linearly with the solvent polarity parameter Z-values. Through this correlation a (new) Z-value of water. 92, was obtained which agrees with the recently obtained value (91.8) .
