A new method is shown to determine C,C spin coupling constants in C 2 symmetric molecules by using proton detection with gradient selected 2QHMBC. It is shown that the pulse sequence proposed distinguishes between symmetric and antisymmetric eigenfunctions of the AAXX spin system.

## 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. From th
