Raman spectroscopy - Wikipedia
Raman spectroscopy (/ ˈrɑːmən /) (named after physicist C. V. Raman) is a spectroscopic technique typically used to determine vibrational modes of molecules, although rotational and other low-frequency modes of systems may also be observed. [1] .

One tool employed to understand the surface chemistry of noble metal nanomaterial, particularly those composed of gold or silver is surface-enhanced Raman spectroscopy (SERS). Replacing a metal surface with a metal nanoparticle increases the available surface area for the adsorption of molecules.
Basic Principles of Raman Scattering and Spectroscopy - Edmund Optics
The Raman spectroscopy technique is one of the most effective methods of determining the chemical composition of a sample via Raman scattering. 3 In this spectroscopy technique, a sample is excited by a monochromatic light source, such as a laser, and the Raman Shifts are collected.
What is Raman Spectroscopy? - Horiba
Raman Spectroscopy is a non-destructive chemical analysis technique which provides detailed information about chemical structure, phase and polymorphy, crystallinity and molecular interactions. It is based upon the interaction of light with the chemical bonds within a material.
Guide to Raman Spectroscopy - Bruker
What is Raman spectroscopy? Raman spectroscopy is based on the interaction of light with the chemical bonds of a substance. This yields detailed information about chemical structure, polymorphism, crystallinity and molecular dynamics.
Raman Spectroscopy - an overview | ScienceDirect Topics
Raman spectroscopy is a nondestructive analytical technique based on the interaction of light and chemical bonds within materials. Raman spectroscopy can provide detailed information on a sample’s chemical structure, phase and morphology, crystallinity, and molecular interactions.
What is Raman Spectroscopy? Principles Overview - Agilent
Raman spectroscopy is a versatile, nondestructive technique that yields detailed information about chemical structure. Raman spectrometers probe materials using monochromatic laser light, usually at visible or near-infrared wavelengths.
Raman Techniques: Fundamentals and Frontiers - PMC
Raman spectroscopy can be used to determine the layer thickness in two-dimensional materials with atomic level precision, using either the inter-layer or intra-layer vibrational modes . Lee et al. demonstrated the technique with two intra-layer Raman modes of molybdenum disulphide (MoS 2).
What is Raman Spectroscopy? - Edinburgh Instruments
Raman Spectroscopy is an analytical technique that uses scattered light to measure a sample's vibrational energy modes. Raman scattering, an inelastic process, provides chemical and structural information, identifying substances via their unique Raman 'fingerprint'.
Raman Spectroscopy - Michigan State University
Raman spectroscopy has become an incredibly useful analytical technique for the identification of organic, inorganic, and biological samples. Raman spectra can generally be measured from solids, liquids, and gases, including thin films and powders.
