 Virtual states not real states and are
created as a result of interaction
 Stokes
 anti-Stokes
 Rayleigh

 Three different light scatter
on the same diagram
 Rayleigh scatter is
sometimes not shown on
diagram
 Raman scatter is a very small
percentage to be captured

 There is little to no sample preparation
 Can analyze organic and inorganic
 Variety samples can analyzed
 Non-destructive to the samples
 Qualitative and Quantitative analysis
 Easy to use
 Expensive
 Laser could destroy sample
