Question

exciting line in an experiment is 5650 Å Stokes line is at 6810 Å. Calculate Wavelength of anti- stokes line .​

Answer 1

are found in fluorescence and in Raman spectra when the atoms or molecules of the material are already in an excited state (as when at high temperature). In I this case the radiated line energy is the sum of the pre-excitation energy and the energy absorbed from the exciting radiation.
