29. They assigned structures which coupled with new signals in the 'H NMR sprectrum as norbornene diads. Nevertheless, no details were given if C2(NN) and C4(NN) coupled over three bonds with hydrogens at Ca(NNE), or if C3(NN) coupled over two bonds with hydrogens at Ca(NNE), and if CKNN) did not couple with hydrogens at Ca(NNE), so that these signals were only diads and not triads.

31. For the calculation of the amount of norbornene centered triads also the integrals of the resonances of Cl, C4, or C5, C6 or C7 may be used.
