Pollutant Identification by Selected Area Electron Diffraction. II. The Limitations

Abstract

Single crystal electron diffraction patterns can be interpreted in a fairly straightforward manner because with a little knowledge of crystallography one can predict the kind of image to be formed by certain minerals. Close agreement between observed and theoretical patterns identifies the particles. However, in practice, electron diffraction patterns can be rather ambiguous or difficult to unravel. Most of the errors are inherent characteristics of certain samples and cannot be corrected easily. The most common of these are the subject of this discussion.
