What is Raman Spectroscopy?

Raman spectroscopy is a vibrational spectroscopic technique that identifies molecules by measuring the scattering of laser light. When a laser beam interacts with a sample, a small portion of the scattered light changes in energy due to molecular vibrations. This change, known as the Raman effect, produces a unique molecular fingerprint that helps identify and characterize substances.

Unlike many analytical techniques, Raman spectroscopy requires little to no sample preparation, making it an efficient and cost-effective solution for many applications.
