Abstract
π-Electronic densities in a series of monosubstituted benzenes I calculated by the PPP method are discussed in relation to the substitution effect of substituent X, to σR0 or σ parameters and to chemical shifts in NMR spectra. π-Electronic characteristics of the compounds I are confronted with electronic and photoelectronic spectra.
