Interpretive Summary:

Technical Abstract: This book chapter covers modern techniques and applications from our laboratory. The headings are: Introduction; Broadness of proton spectra; The sensitivity of modern 2D experiments; A problem with (early) inverse heteronuclear experiments; Advantages of higher magnetic fields; Important classes of 2D spectra; a) Homonuclear correlation (COSY and TOCSY class); b) Homonuclear J-resolved; c) Through-space homonuclear correlation (NOESY/ROESY); d) Inverse C-H correlation (HMQC-class, HMQC-TOCSY); e) Inverse long-range C-H correlation (HMBC-class); f) Carbon-carbon correlation (INADEQUATE experiments); Higher-dimensional spectra; Processing. The Applications are under the headings: Natural lignin esters (acetates, p-coumarates on grasses); Cell wall cross-linking in grasses by ferulates; Products in lignins from mutant or genetically altered plants; Identification of new structures in lignins.
