Quantification of partial structures in aquatic humic substances by volume integration of two‐dimensional 13C nuclear magnetic resonance spectra. Comparison of one‐ and two‐dimensional techniques
Partial structures of a reference groundwater humic substance were quantified by J‐resolved two‐dimensional 13C NMR spectroscopy applied in its phase‐sensitive variant. The results agree with thoseExpand
