The name "Raman spectroscopy" typically refers to vibrational Raman spectroscopy using laser wavelengths which are not absorbed by the sample.

Raman spectroscopy sounds very much like infrared (IR) spectroscopy; however, IR examines the wavenumber at which a functional group has a vibrational mode, while Raman observes …

We briefly explain the fundamentals of Raman spectroscopy and shed light on how the interaction of light with the chemical bonds is used for chemical analysis.

How does Raman spectroscopy work? Learn the fundamentals of Raman, including the Raman effect and Raman scattering, the advantages and disadvantages of Raman, and more.

Raman is a light scattering technique, whereby a molecule scatters incident light from a high intensity laser light source. Most of the scattered light is at the same wavelength (or color) as …

In the following sections, the fundamental physics that underpins the spontaneous Raman effect, stimulated- and coherent Raman spectroscopy, SERS and TERS are detailed in the context of …

Raman spectroscopy is a molecular spectroscopic technique that utilizes the interaction of light with matter to gain insight into a material's make up or characteristics, like FTIR.

Jul 29, 2025 · Raman spectrometry operates on the principle of light scattering, specifically inelastic scattering, or Raman scattering. When light interacts with a molecule, most of it …

Nov 26, 2025 · Raman spectroscopy is an optical technique that detects intrinsic vibrational, rotational and other low-frequency modes in molecules upon inelastic scattering of …

Learn how Raman spectroscopy can reveal the chemistry and structure of materials. We describe the features of a Raman spectrum and explain the variations in Raman band parameters.
