In the present work we give a theoretical explanation of the effect of deuterium substitution on the J13cH coupling constant of a vicinal proton, in tetrahedrally hybridized carbons. The change in tlmeaveraged 2s character of the hybrid carbon orbital, due to the couplin g of the bending vibrations. is cal- culated. The value of the related coupling constant is in good agreement with the experimental one.

## Abstract The one‐bond coupling constant ^1^__J__ ^13^CH for the halogenated carbon in α‐halogenocyclohexanones is more important when the CH bond is in the equatorial then in the axial position. When a conformational equilibrium is present, the resulting coupling is a linear function of the eq
