Coupling Constant Cis Vs Trans at Karen Cutright blog

Coupling Constant Cis Vs Trans. Here are a couple of terms to know: Trans coupling (range :11 to 19 hz) is greater than cis coupling (range: The tables below list coupling constants for a few general cases. But i did not find an explanation for the statement. For coupling the two hydrogens must have different chemical shift. Cis and trans coupling appear differently on 1 h nmr spectrum. Maximum coupling constant (j) occurs at 0˚ and 180˚ (eclipsed and anti protons, respectively), and is at a minimum when they are at 90˚. For more specific cases see these lists. • the vicinal coupling constants across the double bond in alkenes are reasonably distinct! • the cis and trans couplings are both affected.
