Abstract

In the framework of Mulliken's theory a frequency shift in NQR spectra has been considered. It has been shown that in MO LCAO approximation the frequency shift is proportional to the degree of the charge transfer. For the picrylchloride complexes the linearity of this dependence has been confirmed. It has been shown experimentally that the shift is appreciably affected by steric interactions.

Zusammenfassung

Im Rahmen der Mullikenschen Theorie wird eine Frequenzverschiebung im NQR-Spektrum untersucht. Es wird gezeigt, da\ in der MO-LCAO-NÄherung die Frequenzverschiebung proportional dem Grad des “charge transfer” ist. Für Pikrylchlorid-Komplexe wird die LinearitÄt dieser AbhÄngigkeit bestÄtigt. Experimentell wurde gezeigt, da\ die Verschiebung stark durch sterische Effekte beeinflu\t wird.

Résumé

Dans le cadre de la théorie de Mulliken on a étudié le déplacement de. fréquence dans le spectre NQR. Il a été montré que dans l'approximation MO LCAO le déplacement de fréquence est proportionnel à l'importance du transfert de charge. Pour les complexes du chlorure de picryle cette proportionalité a été confirmée par l'expérience. Le déplacement est affecté par ailleurs par les interactions stériques.
