Stacked FTIR spectra for modern untreated willow compared to heavily degraded wood from Star Carr and moderately degraded wood from Must Farm (author’s own data). Commonly used diagnostic peaks relating to cellulose and lignin are highlighted. Degradation can be indicated by relative changes in intensity of these peaks; peak shapes can also change (areas of interest highlighted by dotted boxes)
