## Abstract The oneβbond coupling constant ^1^__J__ ^13^Cο£ΏH for the halogenated carbon in Ξ±βhalogenocyclohexanones is more important when the Cο£ΏH 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
Ab initio calculations using the equations of motion approach are reported for 'J( 13C"C) of the bridgehead bond in [ 1.1.1 I-, 12.1.1 I-, [2.2.1 I-, [2.2.2]-, [3.2.1 ]-propellane, bicyclobutane, bicyclopentane, bicyclohexane and tetracyclopentane. The results give an overall picture of the influenc
