Abstract Three parameters, equation image, equation image and equation image, are developed to express the substituent effect and the effect of the parent molecular structure of p-disubstituted compounds XPh (CH [DOUBLE BOND] CHPh) n Y (n= 0, 1, 2). The investigated result shows a good correlation between the UV absorption wavenumbers (υ max) and the three parameters for a diverse set of title compounds, and the correlation ...
