## Abstract The ^19^F substituent chemical shifts (SCS) of __meta__β and __para__βbenzoyl fluorides are found to correlate well with substituent parameters using the dual substituent parameter (DSP) equation, indicating that they reflect electronic perturbations induced by the substituent. The dire

Ab initio calculations for a series of perfluorinated annulenes suggest that there is a linear correlation between the total charge density at fluorine and the fluorine chemical shift. The STO-30 basis set overestimates the degree of pi-electron donation by fluorine.
## Abstract The ^19^F substituent chemical shifts (SCS) of a series of __para__βphenylacetyl fluorides (Xο£ΏPhο£ΏCH~2~ο£ΏCOF) are reported and compared with the related benzoyl fluoride series (Xο£ΏPhο£ΏCOF). A dual substituent parameter analysis of the results for the new series shows that both inductive an
