摘要:

Γ bands of 23 anion-radicals of meta- and para-substituted benzophenones have been assigned and compared to Γ C=O of the parent neutral compounds. Carbonyl frequencies of the anion-radicals (assigned on the basis of data for isotope-labelling compounds) have been found to appear in a 7–8 times wider frequency interval as compared to the frequency range of corresponding neutral compounds, i. e. the structural effects on Γ on the anion-radicals are 7–8 times stronger, compared to those on Γ C=O of the neutral benzophenones.
