Technology Overview

Raman spectroscopy is a method of measuring frequencies and strengths of molecular vibrations. These frequencies typically belong in the infrared area of electromagnetic spectrum, but Raman spectroscopy allows measuring them using visible of near-IR light. Vibrational spectra of molecules are used to identify different species or crystalline structures of solids.
