L. McHale – Molecular Spectroscopy (Prentice Hall, 1999). Efficient detection of biofilms is important for the clinical management of diseases they cause and for providing an endpoint to clinical treatments. But while infrared measures the amount of IR light absorbed, Raman measures the amount of light scattered. The two strongest are . The energies are reliant on the shape of the molecular surfaces, the associated vibronic coupling, and the mass corresponding to the atoms. 9.
