coherent Stokes Raman spectroscopy
coherent Stokes resonance Raman spectroscopy
CHMO:0000660
Spectroscopy where the Raman scattering of monochromatic light by a sample is detected. An anti-Stokes frequency stimulation beam is used and a Stokes frequency beam is observed and the difference between the pump and the Stokes beams coincides with the frequency of an electronic transition within the molecule. multiphoton excitation is used to produce a signal in which the emitted waves are coherent.
