IUPAC - Raman wavenumber shift (08671)

Raman wavenumber shift symbol: $Δ \tilde{ν}$ , units: $m^{- 1}$ , ${cm}^{- 1}$

Synonym: Raman shift

https://doi.org/10.1351/goldbook.08671

Wavenumber of exciting electromagnetic radiation minus wavenumber of the scattered radiation.

Notes:

SI unit: $m^{- 1}$ . Common unit: ${cm}^{- 1}$ .
$Δ \tilde{ν}$ is positive for Stokes Raman scattering and negative for anti-Stokes Raman scattering.
