The information obtained by HREELS is similar to that provided by infrared and Raman spectroscopy.
Current applications of HREELS include the study of:
In HREELS, a monoenergetic beam of low-energy electrons is focused onto a sample surface.
The most extensive use of HREELS involves identifying adsorbed molecules and molecular intermediates on metal single-crystal surfaces.
Information provided by HREELS is complementary to the compositional information provided by Auger spectroscopy and SIMS and the insights into electronic structure offered by XPS and UPS.
