Rayleigh stokes and anti-stokes scattering
Weblower energy (longer wavelength)- it is the Stokes scattering -or higher energy (shorter wavelength) than the elastic Rayleigh line- it is the anti-Stokes scattering. In each case … WebFind the ratio of intensities of the violet and red satellites, closest to the fixed line, in the vibration spectrum of Raman scattering by C l 2 molecules at a temperature T = 3 0 0 K if the natural vibration frequency of these molecules is ω = 1. 0 6 × 1 0 1 4 s − 1.

WebIf a molecule gains energy from the radiative field, the resulting lower frequency scattered radiation is termed the Stokes component; if the molecule loses energy to the radiative field, the scattered radiation is referred to as the anti -Stokes component. Rayleigh or Raman scattering can occur upon excitation at any visible or ultraviolet ...
WebWe report an epi-detected coherent anti-Stokes Raman scattering (E-CARS) microscope that uses two synchronized picosecond pulse trains. The microscope not only provides high spectral resolution but also significantly improves sensitivity for three-dimensional vibrational imaging of living cells.
