Answer to Question #87598 in Optics for Sridhar

Question

in a Raman experiment excitation line is 18315 /cm and stroke line 18116/cm then anti stoke line

Answer 1

excitation line $\nu_0 =18315\, cm^{-1}$ , Stokes line $\nu_S = \nu_0 - \Delta \nu = 18116 \, cm^{-1}$

Antistokes line $\nu_S = \nu_0 + \Delta \nu = 2\nu_0 - \nu_S = 18514 \, cm^{-1} \Rightarrow \lambda = 540.13\, nm$
