From the USDA NMR Database of Lignin and Cell Wall Model Compounds
A description of these data, collected by Sally Ralph and Larry Landucci at the USDA Forest Products Lab, and John Ralph's group at the USDA Dairy Forage Research Center and (more recently) the UW Biochemistry Department, is available as a pdf file. This includes a description of the naming conventions used as well as experimental conditions and a structure index.
