Abstract [en]

High-resolution 2D HSQC NMR technique was found to be a powerful analytical tool for studies on lignin structure. High resolution in the F1 dimension of an HSQC spectrum can be obtained by proper sample purification and optimized shimming as well as by acquiring large enough increments. By combining the results from 2D HSQC, HSQC-TOCSY and HMBC NMR experiments, novel lignin structures, including spiro-dienone, secoisolariciresinol and neo-olivil have been observed and identified. The concept of quantitative structure determination by applying 2D HSQC NMR technique was investigated. The influence of T-2 relaxation decays, coupling constant, off-resonance effect and homonuclear couplings on NMR signal quantification have been discussed. beta-5 Structure in a lignin sample was accurately determined by using the HSQC NMR analysis through a unique way of selecting the proper internal standard reference signal(s).
