Vibratory ball milling is shown to have a strong influence on the shape of FTIR spectra of wood and cellulose, even if the samples are milled for only a short time. The results show that neither temperature nor particle size or oxidation processes are the most important reason for the observed changes in the structure of the FTIR spectra, but that the mechanical treatment itself is the main ...
