A method of calculating K-shell excitation energy-selected electron diffraction patterns from crystals is described, and examples of calculations are given. The symmetry of these patterns is shown to be equal to that of the entire crystal (and not of the selected sublattice) for perfect crystals, and equal to the local site symmetry for patterns selected from disordered species occupying equivalent sites in the lattice.
