Abstract

Hermans' orientation factor can be evaluated only when the diatropic and paratropic interferences arise from planes which form an orthogonal set. This is only approximately satisfied in case of both cellulose I and cellulose II. In the present communication an exact expression has been derived which can be evaluated from x‐ray measurements, angle between face normals of paratropic interferences, and the optical constants.
