692 A Unified Treatment of Solvent Properties

Abstract

Principal component analysis (PCA) has been carried out with 40 solvent scales as variables, each having 40 data points for 40 solvents as objects. The first three components account for 74 % of the total variance. For 36 of the scales, an average of 88 % of the variance is described by the first three principal components. The solvents and the solvent scales are grouped according to the scores and loadings obtained from PCA treatment. This allows comparison of both solvent scales and characterization of individual solvents
