resonance Raman spectroscopy surface-enhanced resonance Raman spectroscopy surface enhanced resonance Raman spectrometry CHMO:0000670 surface enhanced resonance Raman scattering spectroscopy FIX:0000077 Spectroscopy where the Raman scattering of monochromatic light, from a visible laser, by a sample adsorbed onto a metal (Au, Ag or Cu) surface is detected. The energy of the incoming laser is adjusted such that it or the scattered light coincides with an electronic transition within the sample.
