Zusammenfassung
Die Theorie von Valenzzuständen wird im Zusammenhang mit wahren oder «intrinsischen» (als verschieden von thermochemischen) Bindungsenergien diskutiert.
Mit den augenblicklich zur Verfügung stehenden Kenntnissen können nur annähernde Schätzungen der Energien der Valenzzustände gemacht werden. Dies ist für das Beispiel von vierwertigem Kohlenstoff mit einer Anzahl von unabhängigen Methoden unternommen worden. Der angedeutete Wert ist etwa 60–70 kcal höher als der Grundzustand. Da der Valenzzustand in Beziehung mit der Sublimationswärme des Kohlenstoffs steht, liefert er Belege bezüglich des letzteren.

That the figure 7 eV is much too high, may be readily seen from a consideration of acetylene and its halogen derivatives. The ground state of these molecules is unquestionably X-C≡C-X, but this would be stable relative to X-C-C-X only as long as the difference in the bond-energy sum for the two structures exceeded the sum of the promotional energies of the two carbon atoms. A figure even approaching 7 eV for each atom is accordingly seen to be excluded. SeeL. H. Long, Z. Elektrochem.54, 79 ff. (1950).

A much higher value around 170 kcal has frequently been proposed, but there is no objection-free evidence in support of it, and the weight of the evidence indicates that it can be excluded. From independent considerations,Pauling andSheehan (loc. cit.). also exclude this value. ThatPauling andSheehan favour a value somewhat higher than 125 kcal is due to their assumption that the carbon in the ground state of CN and the lowest triplet state of CO is in the divalent (and not tetravalent) state.

The figure forD(CH3-H) is that given byG. B. Kistiakowsky andE. R. Van Artsdalen, J. Chem. Phys.12, 469 (1944), after correcting for an improved value ofD(HBr) involved in the calculation [cf.L. H. Long, Proc. Roy. Soc. A198, 65 (1949)]. The figure forD(CH3-CH3) follows from this.
