Raman Application Areas

Raman spectroscopy is useful for analyzing molecules without a permanent dipole moment, which does not show up on an IR spectrum. Raman spectroscopy is used to determine bond lengths in non-polar molecules. It is useful for determining the identity of organic and inorganic species in solution, as the Raman transitions for these species are more characteristic than for IR, where the transitions are much more affected by the other species present in the solution. Raman can be used to analyze solid, liquid and gaseous sample components even through glass and plastic containers.
