It yields vibrational spectra of the adsorbates with high resolution (< 0.5 meV) and high sensitivity (< 10 molecules are required to provide a spectrum). An additional advantage is the fact that optically forbidden transitions may be observed as well. Within IETS, an oxide layer with molecules adsorbed on it is put between two metal plates.
