Raman Insights

What is Raman?

Raman spectroscopy is a spectroscopic technique used to observe vibrational, rotational, and other low-frequency modes in a system. It relies on inelastic scattering of monochromatic light, usually from a laser, which means that the energy of the laser photons changes upon interaction with the sample. By analyzing the energy shift and intensity of the scattered light, information about the sample's molecular structure and composition can be obtained. It is commonly used in chemistry, physics, materials science, and pharmaceuticals for identifying substances, analyzing chemical bonds, and characterizing material properties.
