The utilization of the long range optimized proton‐carbon chemical shift correlation experiment in the total assignment of the proton and carbon nmr spectra of 9‐methylphenanthro[4,3‐ a ]dibenzothiophene is described. The experiment was employed in concert with conventional proton‐carbon chemical shift correlation, heteronuclear relayed coherence transfer and broad band homonuclearly decoupled proton‐carbon chemical shift correlation experiments. The experiments in combination offer a useful alternative to the 13 C‐ 13 C double quantum coherence experiments, providing significantly better sensitivity and nearly the same capabilities.
