a nominal HMBC of H9; b i-HMBC of H9; c D-i-HMBC of H9 (2JCH are in red, the most downfield 4JCH are in blue, the isotope shift difference are in magenta); methods to determine chemical shift (d) peak picking, (e) line fitting (blue: fitted peak; pink: sum of fitted peak; red: fitting residue); f stack of horizontal slices of i-HMBC correlations from H9, showing measurements of isotope shift differences.
