    Paradigms and Paradoxes Are Acyl Azides Resonance Stabilized? (1999)
    Springer
    Structural chemistry 10 (1999), S. 327-329

    ISSN: 1572-9001
    Keywords: Acyl azides ; Curtius rearrangement ; enthalpy of formation ; enthalpy of reaction ; phenyl/vinyl thermochemical equivalence, resonance energy

    Notes: Abstract By means of the generic isodesmic reaction C6H5COX + RCH3 → C6H5COCH3 + RX, the phenyl/vinyl thermochemical equivalence, and an experimental determination of the enthalpy of the Curtius rearrangement of acryloyl azide, the resonance energy of acyl azides was ascertained to be ca. 29 kJ mol−1.

    The energetics of ions, atoms, and salts: Sodium and its chloride (1994)
    Springer
    Structural chemistry 5 (1994), S. 341-343 
    Details
    ISSN: 1572-9001
    Keywords: Bom-Haber cycle ; bond energies ; Coulombic attraction ; electron affinities ; ionic bonding ; ionization potentials
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract In this study we reconcile three seemingly contradictory assertions regarding sodium chloride. First, gaseous sodium chloride is Coulombically bound and highly ionic. Second, upon pulling the molecule apart atomic sodium and chlorine are produced. This is somewhat surprising; despite the high ionicity of NaCl, since IP(Na) 〉 EA(Cl). Third, heterolytically dissociating NaCl(g) into Na++Cl+ costs more energy than ionizing gaseous Na into Na++e−. Does this violate Coulomb's law since the Na-Cl bond distance in NaCl(g) is greater than the average Na nucleus-valance electron distance?

    Paradigms and Paradoxes: Electronegativity and Bond Energies—Living Legacies of Linus and Lee (2000)
    Springer
    Structural chemistry 11 (2000), S. 375-378 
    Details
    ISSN: 1572-9001
    Keywords: Bond energies ; electronegativity ; enthalpies of formation and of reaction ; halogenolysis ; hydrocarbons ; lone pair-lone pair repulsion ; organosulfur compounds ; thermochemistry
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract In this paper we will discuss Pauling's classic Eq. (1) that relates bond energies, "D," and electronegativities, "x." Recast to be applicable to enthalpies of formation and reaction, we apply it to the study of hydrogenolysis reactions of dienes, diynes, and alkanes, halogenolysis reactions (with chlorine, bromine, and iodine) and metathetical reactions of organosulfur species (sulfides, sulfoxides, and sulfones). It is with great regret that this equation is found wanting.
