| Abstract | ||
| The complexes of para-chloranil as electron acceptor and the anions of amide, azide and cyanide as electron donors in aqueous ethanol as a solvent, were studied spectrophotometrically . The reactions lead to the formation of charge transfer complexes. The CT complexes were stable in excess acceptor concentration, while they were underwent another transformations in excess donors concentrations. Stoichiometries were determined, the molecular ratio was determined by continuous variation method (Job method) and is was 1:1 (donor: acceptor). The maximum wavelength (λ max.), the energy (hυCT), ionization potential (Ip) and activation energy (w ) of excited state for the charge transfer complexes were calculated, presented and discussed. | ||
