Abstract : From measured photoionization potentials of amines, a new set of constants which quantitatively reflect changes in ionization potential with substituent groups were derived. Using these, ionization potentials of alkyl free radicals could be estimated to within the experimental error of their measurements. There is a saturation effect and these values are not linearly additive but can be combined following certain set precepts. Values obtained from linear and branched alkyl substituents proved to be extendable to cyclic substituents in which the carbon from whence the unpaired electron was being withdrawn was itself part of the ring. However, effects of substitution on ionization potentials are not the same for the series of alcohols and ethers as for the amines. (Author)
