“…The viscosities of the solvent mixtures and the Waiden products of the acids at various compositions are recorded in Table 2. The results show that the acids are practically completely dissociated in these solvent mixtures, which is further supported by the linear plots obtained when plotting A' given by ((2) in [13])…”

“…The conductance data, when analysed with the Fuoss-Onsager-Skinner three parameter equation [13], using an IBM 360 computer, did not indicate any appreciable association of the acids. Hence the data were further analysed with the Fuoss-Onsager-Skinner two parameter equation ((2.7 b) in [13])…”

The influence of solvent on the UV-visible absorption and luminescence spectra of some highly fluorescent vitamin derivatives, the products of the reaction of N-methylated vitamin Bj with cytidine (I), adenosine (II) and 2-amino-4-methylpyridine (III) is studied. Spectroscopic manifestations of protonation of I and II are also investigated using a semiempirical INDO/S CI method. Singlet and triplet energy levels of the free ion and several protonated species are calculated, and transition energies and osci

MUNAN KO, TSUNEYURI SATO, and TAKAYUKI OTSU. Can. J. Chem. 54, 1886Chem. 54, (1976. The decomposition of dimethylbenzylanilinium chloride (DMBAC) was found to follow second-order kinetics in ethanol or aqueous ethanol solvents, but first-order kinetics in higher alcoholic solvents. From the activation parameters obtained at 80 "C, different isokinetic relationships were found for the ethanol series and the higher alcohol series. The dissociation constants of DMBAC in ethanol and isopropanol at 80 "C were calculated to be 7.34 X lo-) and 2.10 X 10-4 mol/l, respectively, from conductivity measurements. Accordingly, it was concluded that in higher alcohols the major part of DMBAC exists as ion pairs, which are responsible for the decomposition reaction, but in ethanol the decomposition involves a bimolecular reaction between free ions. MUNAN KO, TSUNEYUKI SATO et TAKAYUKI OTSU. Can. J. Chem. 54, 1886Chem. 54, (1976. On a trouvC que la cinCtique de L a dCcomposition du chlorure de dimCthylbenzylanilinium (DMBAC) est du deuxikme ordre dans I'Cthanol ou dans des melanges ethanol-eau; cette dCcomposition est toutefois du premier ordre dans des solvants alcooliques de poids molCculaires plus Clevis. A I'aide des paramktres d'activation obtenus 21 80 "C, on a trouvC diffirentes relations isocinCtiques pour les skies Ctl~anoliques et pour ses homologues supCrieurs. On a calculC, B partir de mesures de conductivitC k 80 "C, les constantes de disssciation du DMBAC dans I'Cthanol et I'alcool isopropylique qui sont respectivement 7.34 X 10-3 et 2.10 X mol/l. On en conclut donc que, dans les alcools de poids molCculaires plus ClevCs, la portion principale du DMBAC existe sous fornle de paire d'ions qui sont responsables pour la reaction de dCcomposition; dans I'Cthanol, la dCcomposition implique une rCaction bimolCculaire entre ions libres.[Traduit par le journal]

“…This is the reason why mean-field approximations, despite ignoring ion-ion correlations, continue to be the basis of the theoretical understanding of many phenomena like ionic and colloidal stability, electrolyte solutions thermodynamics and phase transitions in ionic fluids. On the other hand, almost all our theoretical understanding of charge transport in ionic fluids is almost completely constrained to dilute ionic solutions, for which the so called Debye-Hückel-Onsager or Onsager-Fuoss theory was originally developed (for the series of results which constitute this theory see (Fuoss et al, 1965) and references therein). This framework is built on the structural basis of the Debye-Hückel model of ionic solutions, and therefore the basic structural feature continues to be the ionic atmosphere.…”
