Summary
The general quadratic force field for the in-plane vibrations of isophthalonitrile was calculated by the semi-empirical MINDO/3 method. This force field was refined to the frequencies observed experimentally for isophthalonitrile and isotopic shifts of isophthalonitrile-15N2. The normal coordinates and the force field in internal coordinates were also calculated from the refined field.
Zusammenfassung
Das allgemeine quadratische Kräftefeld für die nichtebenen Schwingungen von Isophthalsäuredinitril wurde mit der halbempirischen MINDO/3-Methode berechnet. Das Kräftefeld wurde aufgrund der experimentalen Frequenzen von Isophtalsäuredinitril und der Isotopen-Verschiebungen von Isophtalsäuredinitril-15N2 verfeinert. Die Normalkoordinaten und das Kräftefeld in inneren Koordinaten wurden auch vom verfeinerten Kräftefeld berechnet.
