inelastic electron tunnelling spectroscopy

initialism: IETS
https://doi.org/10.1351/goldbook.08616
Measurement method of vibrational spectroscopy to obtain spectra of molecules on metal oxide surfaces.
Note:
IETS yields vibrational spectra of adsorbates with high resolution (better than \(\pu{0.5 meV}\)) and low limit of detection (below \(\pu{E13}\) molecules are required to provide a spectrum).
