Figure 8.

Long-range heteronuclear QuILTs summarize both the observed direct (¹J_C,H) and ^≥2J_C,H correlations in the original (A; HETCOR and long-range HETCOR, respectively) vs revised (B; HSQC and HMBC, respectively) aquatolide structures. The numbers inside the δ and atom number grid reflect the number, n, of connecting bonds (ⁿJ). Bolded numbers represent observed correlations. Color coding of boxes: black = one bond, violet = two bonds, blue = three bonds; white = four and more bonds. Color coding of numbers: black and white = ¹J_C,H correlation; gray ^≥2J_C,H correlations.
