Nuclear magnetic resonance organic matter

Wilson et al. [2] carried out a compositional and solid state nuclear magnetic resonance (NMR) spectroscopic study of humic and fulvic acid and fractions present in soil organic matter. [Pg.282]

Although soil organic matter has been extensively studied by spectroscopic methods, very few investigators have studied peat as a source of humic substances (5-8). This paper presents carbon-13, proton nuclear magnetic resonance (l c-NMR and H-NMR) spectra,... [Pg.384]
