The identification of groups of chemically inequivalent
protons and carbon atoms observed in the 1
H NMR, 13C
NMR, HMQC, and COSY spectra of Λ-(or Δ-)Co(diNOsar)
is straightforward; however, mapping out those sets onto the
3D structure of the molecule and differentiating between the
cap and ethylene bridge protons is more challenging. For
