Notes:
A CBED (convergent-beam electron diffraction) method proposed by the present authorsfor chiral identification of enantiomorphic crystals has been successfully applied to intermetalliccompounds with the point groups of 23, 422, 432 and 321. The intensity asymmetry of ZOLZand/or FOLZ reflections of the Bijvoet pairs is easily recognized in CBED patterns with theincidence along the appropriate zone-axis orientations for each of the two members of theenantiomorphic pair and the intensity asymmetry with respect to the symmetry line is reversedupon changing the space group (handedness) from one to the other. Thus, the generality of theproposed method in identifying the chirality for all crystallographycally possible enantiomorphiccrystals is verified
