Silicon-29 nuclear magnetic resonance (NMR) spectroscopy has been used to investigate the equilibrium distribution and kinetics of silicate oligomers in aqueous tetraalkylammonium silicate solutions. Certain tetraalkyl ...

NMR problems related to assignment techniques and relaxation restrict the use of NMR in the structural analysis of lignin. These problems have been addressed in three practical studies in this thesis involving a lignin ...
