1 H and 13 C NMR assignments of bipyridine helicate complexes and their precursor ligands were achieved using gradient‐based homo‐ and hetero‐correlated 2D experiments. The observed trends in 1 H and 13 C chemical shift variations [Δδ(H) and Δδ(C)], on passing from the ligands to the complexes, are accounted for on the basis of MO evaluation of atomic charges.
