The diffractometer measurement of twinned and clustered crystals requires an accurate knowledge of Q i = U i B i matrices of single‐crystal individuals contained in the sample. A determination of the Q i matrix is best done from several accurately centered orienting reflections diffracted by the i th single‐crystal individual. The assignment of the orienting reflections to the individuals is easy for well resolved reciprocal lattices; for closely superimposed ones a method is presented which facilitates this assignment.
