## 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 ^13^C __T__~1ρ~ values measured for isobutylamine, diethylamine, pyrrolidine, piperidine and triethylamine yield one‐bond ^14^N^13^C coupling constants and ^14^N spin‐lattice relaxation times. A decrease of ^1^__J__(^14^N^13^C) was observed in sterically hindered secondary amines.
