Raman Spectroscopy

Question 1

Define Raman Spectroscopy

Answer 1

It’s a chemical analysis technique (scattering technique)

Question 2

What’s the three processes that could occur during light scattering?

Answer 2

1. Rayleigh scattering
2. Stokes Raman scattering
3. Anti stoke Raman scatterin

Question 3

Rayleigh Scattering

Answer 3

1. Before irradiation nearly all electrons are in the ground vibrational level of their electronic ground state
2. Electrons excited by laser however, not high enough to raise to their next highest electron energy level
3. Loosing energy = electrons return to their electronic ground state releasing energy
