NEW EXAMPLES FOR NEAR-EDGE FINE-STRUCTURES IN ELECTRON-ENERGY LOSS SPECTROSCOPY

The electron energy loss near-edge structures of the K and L edges of elements occurring n sulfides and oxides of copper and zinc have been investigated. Furthermore, the K edge of carbon in some carbonates and the L edges of sulfur and phosphorus in sulfates and phosphates have been measured and the near-edge fine structures of these edges have been found to be characteristic for the complex ions CO//3**2** minus , SO//4**2** minus and PO//4**3** minus . Thus, near-edge fine structures of EELS edges can be very useful as a fingerprint for rapid identification of chemical compounds such as carbonates, sulfates, phosphates and some oxides in the TEM.
