配件 2As the spectrometer’s laser interacts with a sample, the energy of the light scattered back is shifted resulting in a Raman spectrum that gives valuable information about the chemical structure. This article covers some of the most frequently asked questions about Raman spectroscopy regarding the theory behind it and how it can be used in practice.
Click on a question below to jump directly to that subject:
Raman is a form of molecular spectroscopy that is observed as inelastically scattered light when a sample is excited by a laser. While most scattering occurs elastically, about 1 in 106 scattering processes interact with the molecule through bond stretching and bending vibrations resulting in Raman-scattered light. Shifted by these molecular interactions, the detected Raman photons can be processed into a spectrum that relates to the unique bonds within a molecule, providing the user with an invaluable analytical tool for molecular fingerprinting. This «fingerprint» is used primarily for material identification and, increasingly, for quantification.
