Summary The paper describes the retention changes observed when an organic acceptor is added to the mobile phase of a liquid chromatography system. The capacity factor decrease depends on the donor character of the solute. Correlations with ionization potentials, HOMO energies and half wave oxidation potentials demonstrate the role of the organic acceptor. According monstrate the role of the organic acceptor. According to the chromatographic properties of the acceptor which is either unretained (TCNE) or slightly retained (TNF) different retention mechanisms are proposed.
