A method for finding the unit cells from the d values of powder patterns of monoclinic substances is described. An appropriate computer program based on this method is developed and combined with an already existing program [Kohlbeck & Hörl, J. Appl. Cryst. (1976). 9 , 28–33] which has treated monoclinic cells as triclinic. In this way, calculation times are obtainable for monoclinic cells approximately five times shorter than those obtained with the previous program alone.
