WebThe Problem of Raman Scattering. To illustrate the problem that Raman scattering can cause, the fluorescence spectrum of a dilute solution of fluorescein in aqueous PBS buffer (pH 7) was measured using the … WebA typical cross-section for Rayleigh scatter is 10-28 cm2 sr-1. Because Rayleigh depends upon the fourth power of the frequency, the value will vary a bit. A typical cross-section for Raman scatter is 10-30 cm2 sr-1. Again the exact value will depend upon the excitation frequency and distance from the absorption band. solidworks optical simulation

"WebRayleigh scattering of sunlight in Earth's atmosphere causes diffuse sky radiation, which is the reason for the blue color of the daytime and twilight sky, as well as the yellowish to reddish hue of the low Sun. Sunlight is also subject to Raman scattering, which changes the rotational state of the molecules and gives rise to polarization effects. " - Rayleigh mie raman scattering
