Inelastic electron tunnelling spectroscopy

  "id": "MLC-T-CHM-005812",
  "term": "Inelastic electron tunnelling spectroscopy",
  "field": "Chemistry",
  "definition": "A spectroscopic technique that probes the vibrational modes of molecules adsorbed on a metal surface by measuring changes in the tunneling current across a metal-insulator-metal junction. Electrons tunnel through the insulator, and some lose energy by exciting molecular vibrations. This method provides high-resolution vibrational spectra, particularly for species at interfaces.",
