## Abstract Temperature dependence of __cis__β and __trans__βvicinal spinβspin coupling constants of substituted cyclic 5βmembered compounds is discussed. The temperature dependence of __trans__βvicinal coupling constants is shown to be essentially stronger than that of __cis__βvicinal coupling con
The magnitude of the 45 proton-proton coupling constant across the fragment CH3-C-C-H (a probe of the bond order between the central spz-sp2 hybridized carbon atoms) has been found to be essentially independent of substitution on a toluene fragment and on the size of the ring containing the ortho-al
## Abstract The increments in ^3^__J__(Cο£ΏH) for substituents attached to C^Ξ³^ in the ^13^C^Ξ±^βC^Ξ²^βC^Ξ³^β^1^H coupling pathway, with respect to ^3^__J__(Cο£ΏH) in propane are calculated for equal C^Ξ²^βC^Ξ³^ rotamer population from ^3^__J__(Cο£ΏH) observed in the corresponding neopentyl compounds.
