摘要：

Z values are reported for 41 solvents, thereby almost doubling present knowledge. Linear correlations among Z, Y, log kion, χB, Ω, and F solvent polarity scales have been examined statistically. Correlation coefficients are greater than 0.95, and it is shown that solvent polarity values may be predicted to within a few percent. The Z value for water is reexamined and a new lower value of 91.8 kcal-mole-1 is advocated. © 1979 Plenum Publishing Corporation.
