WebbRaman waveshift converter. Home / Raman waveshift calculator. This raman shift calculator converts between Raman shift in inverse cm and wavelength in nm. Laser … WebbRaman spectroscopy is the inelastic scattering of laser photons, by excitations such as symmetric breathing modes in molecules or phonons in crystalline solids. We are measuring the loss (or gain) in photon energy upon the creation (or annihilation) of such an excitation. These energies are typically ≈ 100 meV.
