## Abstract Geminal ^15^N^13^C coupling constants have been measured in a series of ^15^N‐enriched 1‒phenyl‒3,5‒dialkyl‐substituted pyrazoles. The importance of the orientation of the nitrogen lone‐pair in determining the magnitude of ^2^__J__(^15^N^13^C) values is reflected in the enhanced coupli

## 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
## Abstract ^1^__J__(^13^CH) and ^2^__J__(^13^CH) involving the aldehydic proton in __ortho__‐alkylbenzaldehydes have been examined for evidence of a hyperconjugative contribution from the aromatic π‐electrons. The expected hyperconjugative effect is obscured by changes in the coupling constants re
In this work it was sought to explore the versatility of geminal spin-spin coupling constants, 2 J XY SSCCs, as probes for stereochemical studies. A set of compounds, where their experimental 2 J XY SSCCs through the X-C-Y molecular fragment are predicted to be sensitive to hyperconjugative interact
