    Notes: Abstract The excess Gibb's free energy of mixing, GE, for ethyl iodide+toluene at 25°C have been obtained from the measured vapor pressuure data. The HE and GE values for ethyl iodide+toluene are positive throughout the ethyl iodide concentration range and GE〉HE. The results have been analyzed in terms of Flory and ideal associated model theory of nonelectrolyte solutions. It has been observed that the ideal associated model approach which assumes the presence of AN and A2B molecular species describes well (within±10 J-mol−1 in the worst case) the general dependence of HE on XA (mole fraction of ethyl iodide) over the whole composition range for ethyl iodide+toluene mixtures. The equilibrium constants for A+A⇆ AB and 2A+B⇆A2B reactions along with the enthalpies of formation of AB and A2B molecular species have been calculated.

    Oscillator strengths for P V, S VI, Cl VII, Ar VIII and K IX (1993)
    Springer
    Il nuovo cimento della Società Italiana di Fisica 15 (1993), S. 77-85 
    Details
    ISSN: 0392-6737
    Keywords: General theory of electronic structure ; electronic transitions and chemical binding

    Topics: Physics
    Notes: Summary Optical-oscillator strengths, of both the length and the velocity forms, for the inner-shell excitation 1s 22s 22p 63s 2 S e→1s 22s 22p 53s 2 2 P o transition, which leads to autoionization (Auger transition), in P V, S VI, Cl VII, Ar VIII and K IX ions of the sodium isoelectronic sequence have been calculated using the approach suggested by one of us (Tiwary) in the case of the Fe XVI ion. Our present calculated results demonstrate that the Tiwary approach is capable of yielding encouraging results.
