Abstract An ionic, i. e. essentially electrostatic, approximation to donor-acceptor bonding between neutral species, ion-molecule interactions and corresponding solvation effects is forwarded. Drago's E-C equation for donor-acceptor reactions and the elimination of solvation procedure (ESP), presented by Drago et al., can consistently by incorporated in the general scheme. The theory yields further correct values for bulk ion-solvation enthalpies of cations H+,Li+,Na+,K+,Rb+ in water with the aid of ionization energies and electron affinities only. The formulae deduced for these types of chemical bonding represent the equivalent of the electronegativity-based theory for the description of ordinary chemical bonding between atoms, introduced earlier.

Coulomb Integrals

AbstractThe linear combination bond orbitals (L.C.B.0.) MO treatment has been used to reproduce the π ionization energies of several ortho-, meta-and para-disubstituted benzenes. The Coulomb integral of the substituent π orbitals and their resonance integrals with the ring π orbitals have been obtained from the spectra of the corresponding monosubstituted benzenes, using the same procedure for all the compounds under examination. The ring Coulomb integrals have been chosen taking, as an internal standard, the experimental ionization energy value of the π[a2) orbital, non interacting by symmetry in the monosubstituted and in the para-disubstituted compounds. An application of this simple method to conformational analysis and to electron affinities is also shown.
