## Abstract The ^1^__J__(SnC)s in the tin–carbon double‐bond systems were determined for the first time. These results were supported by theoretical calculations, showing the high s‐character of the SnC double bonds. The new findings obtained will be of great use in the development of tin‐contain

## Abstract Theoretical nuclear spin–spin coupling constants are calculated using mutual and self atom–atom polarizabilities according to a theory where no semi‐empirical parameters are used, except Slater exponents which can be obtained from other sources. As an application, the ^13^CH and HH′ c

## Abstract The one‐bond coupling constant ^1^__J__ ^13^CH for the halogenated carbon in α‐halogenocyclohexanones is more important when the CH 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
