L'auteur decrit une methode de mesure de la pente a mi-onde d'une courbe polarographique. La methode est basee sur la superposition d'une faible tension alternative (de l'ordre de 0.005 volt) a la difference de potentiel appliquee a la cellule polaro

L'auteur definit la notion de „pente a mi-onde” d'une courbe polarographique. Il montre par la voie du calcul que dans des conditions experimentales identiques la pente a mi-onde est proportionnelle a la concentration de la substance reduite a l'

Nous avons etabli une methode et decrit une technique permettant de determiner directement le terme d'un titrage potentiometrique ou conductometrique. l'emploi de l'indicateur electrotitrimetrique ainsi realise permet de reduire la duree de ces titra

The energy of inner-sphere reoganization of univalent anions in photoionization in aqueous solution is calculated from a multipole expansion accounting for ion-solvent electrostatic interaction. Only terms pertaining to nuclear motion are retained to

The energies of the lowest ionization band of eight liquids of low vapor pressure are determined from energy distribution curves (EDC), quantum yield spectra (collected electrons per incident photon as a function of photon energy), and second derivat

Threshold energies E t are determined for 14 weak acids and three bases and their ions. Values of E t are interpreted in terms of dissociation or protonation reactions involving species produced by photoionization. Electron transfer to weak acid mole

He(I) photoelectron spectra of liquid 1,2-ethanediol were recently obtained by means of two different techniques: (i) irradiation of the liquid film on a rotating disk target and determination of energy distribution curves with a simple retarding pot

Dielectric dispersion causes the outer-sphere reorganization free energy to vary with photon energy in optical electron transfer. The resulting distortion of the spectral response for photoelectron emission may yield misleading evidence about the emi

Threshold energies Et are determined for photoelectron emission by 20 inorganic anions in aqueous solution (7.1 < Et < 9.1 eV). Calculated values of Et for Cl−, Br−, I− agree with experiment. The Et are correlated with charge-transf absorption
