Raman Spectroscopy

Raman spectroscopy is a spectroscopic technique typically used to determine vibrational modes of molecules, although rotational and other low-frequency modes of systems may also be observed. Raman spectroscopy relies upon the inelastic scattering of photons, known as Raman scattering. A source of monochromatic light, usually from a laser in the visible, near-infrared, or near ultraviolet range is used, although X-rays can also be used. 

Raman spectroscopy is frequently used to identify incoming goods in pharmaceutical manufacturing and QC laboratories.

Handheld Raman spectrometers are used in the field to identify explosives, narcotics, toxic industrial chemicals, chemical warfare agents, and other hazardous substances.
