Rayleigh one-two photon, dipole approx

  1. Aug 7, 2008 #1
    Hello
    Im having 2 questions
    I'm investigating NIR light propagation in tissue such as the skin and my question is:

    In dipole aprox: Absorption, emission and normal Raman scattering is one-photon processes. But what is Rayleigh scattering?

    When light hit a small molecule the dipole approximation is good. But what if the single molecule
    is large like a protein. What happens then to the absorption/emission/raman transitionprobability (fermis golden rule, Kramer-Heisenberg disp relation)?
