“…This triplet configuration will mix with others with excitation 4i + d t . The reduction of the energy for the resulting triplet wave function with the dominant 48 + 49 excitation will be approximately given [22] by the mean of (Mc89,89 -A;) and (M&,89 -A',). Taking the corresponding values from Table 11, we can estimate that this triplet wave function will be more stable than the HF wave function by about 0.1 eV.…”

“…vom 2,6-Naphthochinon IS] oder Diphenochinon [6]. In diesem Zusammenhang wurden INDOund .rr-SCF-Berechnungen des 2,7-Pyreiichinons (9) und des 13.13,14,14-Tetracyano-2,7pyrenchinodimethans (9a) durchgefuhrt [7]. Die Synthese und die elektrischen Eigenschaften von 9a wurden von Cowan et al [8] und Katz et al ", I beschrieben; es erwies sich als schr instabil.…”

“…Die Synthese und die elektrischen Eigenschaften von 9a wurden von Cowan et al [8] und Katz et al ", I beschrieben; es erwies sich als schr instabil. Nach den Rechnungen von Vogler und Bohm [7] sollte die Elektronenaffinitat von 9 (EA = 3,4 eV) nur wenig unter der fur 9a (EA = 3,6 eV) liegen. Der Unterschied diirfte also wesentlich geringer sein, als aufgrund der Werte fur 1,4-Benzochinon (EA = 1,8eV) und TCNQ (EA = 2,s eV) [lo] zu erwarten.…”
