A NEW FORMULA FITTING THE IONIZATION ENER GIES OF THE ORGANIC HOMOLOG

This paper presents a new fitting formula about the ionization energie s of organic homologue: NlogI(p) = a + bn, where N, I-p, and n are tot al atom numbers composing the homologue, ionization energy, and number s of the repeat unit, respectively, and a, b are constants related to the energy level. After making linear regression analysis between Nlog I(p) and n, all the correlation coefficients obtained from 150 groups of photoelectron spectral data of 46 homologous series are higher than 0.997, and among them are 1.000 in 131 groups, so the excellent rate is 100 percent.
