Fluorine—Fluorine Spin—Spin Coupling Constants in Aromatic Compounds: Correlations with the Delocalization Index and with the Internuclear Separation.

A study of orientation effects of electr

A study of orientation effects of electronegative substituents on vicinal carbon-proton spin-spin coupling constants and the correlation of the latter with proton-proton coupling constants in the individual rotamers of 13CH3-C(X)1H-C(Y)1H2 fragments

## Abstract Orientation effects of electronegative substituents on vicinal carbon‐proton coupling constants are studied in 1,2‐disubstituted propanes and are found to resemble those on vicinal proton‐proton coupling constants. Known relations for the orientation effect of substituents on synclinal
