## Abstract The increments in ^3^__J__(CH) for substituents attached to C^γ^ in the ^13^C^α^‐C^β^‐C^γ^‐^1^H coupling pathway, with respect to ^3^__J__(CH) in propane are calculated for equal C^β^‐C^γ^ rotamer population from ^3^__J__(CH) observed in the corresponding neopentyl compounds. From th
## Abstract Proton magnetic resonance spectra of several mono‐ and disubstituted benzaldehydes were studied using CW, INDOR and double resonance techniques. It was verified that substitution in the __para__ position has no effect on the long‐range coupling of the aldehydic proton with the ring prot

## 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
