Measurement method of vibrational spectroscopy in which a constant-energy beam of electrons passes through or is reflected from a sample and the energy distribution in the transmitted or reflected beam is analysed to give a spectrum of number of electrons against electron energy loss.
Note: EELS is used for the study of electronic states and has an energy resolution of \(\pu{0.25 eV}\) or better (corresponding to an approximate wavenumber of \(\pu{2000 cm-1}\)).
