Frequently asked questions
Which type of light is used for Raman spectroscopy?
Raman spectrometers typically use light in a spectrum ranging from infrared to visible and ultraviolet light to measure energy shifts corresponding to vibrational modes. Alternatively, X-rays are used in a technique called X-ray Raman scattering to measure excitations from deep core electrons.
What is Raman spectroscopy?
Raman spectroscopy can be used to measure rotational or vibrational modes using a monochromatic light source, typically provided by a laser. When photons interact with molecules, they can scatter inelastically after exciting a molecules' energy state and relax to another state. The spectrum can be constructed from the differences in wavelengths between incoming and scattered photons. The corresponding energy shifts can be related to specific vibrational modes to characterise the molecule.
What are Raman spectrometers used for?
Raman spectrometers can be used to measure a chemical fingerprint for substances, in particular to detect specific molecules. This technique is sensitive and with lasers can be even used to perform measurements from a distance or inside containers. In addition to chemical analysis, raman spectrometers can also be used to measure temperature and determine the crystallographic orientation of crystalline materials or obtain information on their composition through measuring characteristic phonon modes.
