Title: surface-enhanced hyper-Raman spectroscopy
Long Title: IUPAC Gold Book - surface-enhanced hyper-Raman spectroscopy
DOI: 10.1351/goldbook.08687
Status: current

Definition
Measurement method of Raman spectroscopy by which the Raman spectrum is significantly enhanced simultaneously by both the hyper-Raman (see hyper-Raman spectroscopy) and surface-enhanced Raman (see surface-enhanced Raman spectroscopy) effects.

Note
Very high enhancement factors of \(\pu{E20}\) have been claimed.
