Spectroscopic and chemical characterizations of molecular size fractionated humic acid
TL;DR: Characterization by IR, and CPMAS C-13 NMR spectroscopy indicated that the molecules of the fraction of >/=100 000 daltons were primarily aliphatic, while the smaller molecule of the>/=10 000 dalton fraction were predominantly aromatic.
