Oligomer method meaning of calculated properties
Die geometrische Zelle (G-Zelle) Sie ist durch
starre Ebenen begrenzt, die durch die
Mittelpunkte der Bindungen zwischen benachbarter
Zellen verlaufen.
Die Ladungszelle (L-Zelle) Sie ist durch zwei
Ebenen begrenzt, die senkrecht zur Oligomerachse
stehen, und die so gewählt werden, daß die
gesamte Ladung (Summe der elektronischen Ladung
und der Kernladung) jeder Zelle Null ist.
Die Kristallzelle (K-Zelle) Diese Zelle hat
eine über mehrere Zellen des Oligomers
verbreitete elektronische Ladung. Für die
Berechnung ihrer Eigenschaften wird über alle
Beiträge summiert, an welchen Basisfunktionen
teilhaben, die zu den Atomen der Zelle gehören.
