Calcul a priori des deplacements chimiques en RMN du 19F.2. Amelioration et extension du modele previsionnel pour les molecules saturees

The quality of the earlier described model for predicting the chemical shifts of 19F nuclei in linear saturated molecules is appreciably improved by using as reference some 19F nuclei selected according to the objective criteria of optimization. The model is extended to non-perfluorinated linear carboxylic acids and to branched molecules.
