If we cannot use 1 H or 13 C NMR to analyze lignin, at least not easily, and it does not really contain any other useful NMR active nuclei, ... There is a peak for the phosphitylated cyclohexanol, ...

Lignin (an aromatic macromolecule in biomass), the only renewable source of aromatics, is currently treated as waste and under-utilized. A more appealing and value-added use of lignin is as a ...

NMR spectroscopy has been used to study the molecular structure and chemical dynamics of a vast range of ... The recognizable features in an NMR spectrum show up as distinct peaks of varying height.

Two-dimensional NMR spectra have two frequency axes, which can correspond to like nuclei (i.e. 1H-1H) or different nuclei (i.e. 1H-13C), and a third dimension of peak intensity. More recently, NMR ...

Reductive catalytic fractionation (RCF) is an efficient method for extracting and depolymerizing lignin. Jake worked on identifying catalyst performance differences for RCF without added hydrogen gas.
