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 0.5 meV) and low limit of detection (below 1013 molecules are required to provide a spectrum).
