A diffractometer technique for determining the orientation of single crystals is described. The technique is well suited for small spherical or nonabsorbing crystals, as well as for large, extended‐face crystals and boules. Since the orientation is determined in a plane perpendicular to the plane of incidence of the diffractometer, the technique does not require an accurate knowledge of the lattice parameter for cubic crystals. The c / a ratio or all cell parameters must, however, be known accurately for crystals of lesser symmetry. It is shown that the orientation can be determined to within 0.005°. Factors affecting the precision of the technique are discussed.
