inverse Raman scattering

https://doi.org/10.1351/goldbook.08625
Raman scattering showing absorption when Stokes Raman scattering exceeds anti-Stokes Raman scattering, in an experiment in which a sample is simultaneously illuminated by coincident beams from a continuum source and a pulse laser at ν~0. Energy is absorbed from the continuum at ν~0+ν~s where ν~s is the wavenumber of a Raman-active vibration in the sample that is excited by this process, and this energy is emitted at ν~0.
