Effect of Deuterium Exchange in Lignin on Its Structural Analysis Using FT-Raman Spectroscopy
In lignin structural analysis, 1H-nuclear magnetic resonance (NMR) spectroscopy is frequently applied using dehydrogenative polymer (DHP) . However, this technique has a disadvantage of long measurement time. On the contrast, Fourier transform (FT) Raman spectroscopy has an advantage of short measurement time and gives the information on various molecule structures similar to NMR. However, peak assignment on the FT-Raman spectrum is difficult because of the peak shift by the surrounding environment for the target structure.
