Abstract

The charge distribution of organic acids, alcohols, chinuclidines and phosphonic acids has been calculated by the Omega-HMO(Pi + Sigma) method. A linear correlation was found between the net charge of the acidic hydrogen atoms of organic acids, alcohols and phosphonic acids and the acidity of these compounds. The calculated net charge of the nitrogen atom of chinuclidines is related to their basicity.

Zusammenfassung

Unter Anwendung der Omega-HMO(Pi + Sigma)-Methode wird die Ladungsverteilung in Carbonsäuren, Alkoholen, Chinuclidinen und Phosphonsäuren berechnet. Die Nettoladung der aciden Wasserstoffatome von Carbonsäuren, Alkoholen und Phosphonsäuren zeigt eine lineare Beziehung zu den pK a-Werten dieser Verbindungen. Die berechnete Nettoladung am Stickstoff-Atom der Chinuclidine kann zu deren Basizität in Beziehung gesetzt werden.
