Complexes moléculaires d'hétérocycles soufrés et oxygénés. Étude spectrophotométrique de bandes de transfert de charge multiples

摘要: As with benzenoid donors, the electronic absorption spectra of molecular complexes simple or condensed sulfur oxygen-containing five-membered heterocycles TCNE (or DDQ) often show two charge-transfer bands. In many cases, knowledge actual frequencies requires a technique resolution. The results so obtained are correlated ionization potentials donors on one hand, and refractivity nonpolar solvents other hand.
