Raman Spectrometers

About Raman Spectrometers

Raman spectrometers measure the wavelength and intensity of inelastically scattered light from molecules. They are used to determine the chemical composition of a sample based on the wavelength and intensity of the light passing through the sample. Raman spectroscopy is based on the theory of Raman scattering, which states that light is scattered due to the vibrations of the molecules in the substance or substrate through which light passes. This vibration scatters the light and changes its energy from that of the incident light. In this way, Raman spectrometers use the Raman effect by comparing the different energies of the incident light and the scattered photons.

Raman spectrometers are similar to infrared (IR) spectrometers in that both an IR spectrometer and Raman spectometer measure the vibrational energies of the molecules in a sample. Infrared spectroscopy or IR spectroscopy measures the absorption of light of certain energies that correspond to the vibrational energy of the molecule. Since Raman scattering is different from infrared absorption, the two methods of spectroscopy are often used to provide complementary data.
