Crystalline modifications of cellulose. Part IV. Determination of x‐ray intensity data

The intensities of x‐ray reflections from ordered regions of Cellulose I (ramie) an Cellulose II (Fortisan) have been determined by photometering the x‐ray diagrams. The results are reported as intensities of resolvable reflections, to provide a basis for comparison with postulated crystal structures to be described in Part V of this series. In many cases reflections from several crystallographic planes could not be resolved and the total intensity for the group of reflections is given. This procedure does not make full use of the experimental results; the factors which would have to be taken into account in a more complete interpretation of the data are discussed.
