why ??? if you are correct what happens to the incident photon and where does the new photon come from ?

That is the argument if scattering is defined as an intereaction between a photon and electron causing a change of direction and a possible change of wavelength, flourescence is a form of scattering, regardless of the time difference. I would also note there is a time delay with Raman especialy if a phonon is involved.

Is it possible to have a shadow effect within a crystal latice at a atomic level ? ie can one atom be shielded from the effects of photons by a intervening atom.

Can anyone please settle an ongoing dispute..... Is fluorescence a form of scattering like Raman or not ?
