Polarised Raman micrsospectroscopy was employed to study the molecular structure within dislocations (slip planes) in the cell walls of Hemp fibre cells (Cannabis sativa (L.)). It was found that the cellulose microfibrils within dislocations have a different orientation than in the surrounding cell wall, and that the cellulose in the transition zones between a large dislocation and the surrounding wall may have yet another orientation. Furthermore, cellulose orientation seemed to be less uniform within dislocations than in the surrounding cell wall. (c) 2013 Elsevier Inc. All rights reserved.
