## Abstract The ^1^__J__(SnC)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 SnC double bonds. The new findings obtained will be of great use in the development of tin‐contain

## Abstract ^13^C chemical shifts and ^13^CH coupling constants for classical and non‐classical structures of some typical carbonium ions have been calculated by the method of summation over excited states in the INDO approximation using a special parameterization. Comparison of the data obtained w
## 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
## 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^CH and HH′ c
## 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
