Overview
Raman Spectrometry is a spectroscopic analysis technique used to determine the molecular structure and chemical content of matter through the analysis of laser light scattering. A monochromatic laser beam passing through matter will scatter some light at different wavelengths, creating a Raman spectrum that is specific to the material.
Raman Spectrometry is used for analyzing and identifying chemical compounds, molecular structures, and material phases without damaging the material. Raman spectroscopy is used in several fields, such as polymers, pharmaceuticals, semiconductors, nanomaterials, and biomedical research.
