Abstract
We report an experimental and theoretical (PPP method) study of the UV absorption spectra of 2-azaanthracene and four of its methyl-substituted derivatives. We find that the p bands of these compounds consist of two different vibronicππ * bands. Our experimental and theoretical results suggest a rule for evaluating the effect of methyl groups onπ →π * transition energies as a function of theπ charge on the atoms. We interpret the reasons for the different effects of a polar solvent and hydrogen bonding on theππ * bands of these compounds.
