Abstract:
This work shows the applicability of two‐dimensional (2D) 1 H‐ 13 C heteronuclear correlation (HETCOR) nuclear magnetic resonance (NMR) spectroscopy to the characterization of whole soils. A combination of different mixing times and cross polarization (CP) methods, namely Lee‐Goldberg (LG)‐CP and Ramp‐CP are shown to afford, for the first time , intra‐ and inter‐ molecular connectivities, allowing for molecular assemblage information to be obtained on a whole soil Our results show that, for the brackish marsh histosol under study, two isolated domains could be detected. The first domain consists of O‐alkyl and aromatic moieties (lignocellulose material), while the second domain is comprised of alkyl type moieties (cuticular material). The role of these domains is discussed in terms of hydrophobic organic compound sorption within soil organic matter (SOM), including the possible effects of wetting and drying cycles.
