What Raman spectroscopy can tell you
Raman spectroscopy produces chemical and structural information to help us understand more about the material being analysed. This page details some of the benefits of Raman spectroscopy.
Identify unknown materials
We can identify unknown materials from their unique Raman spectral fingerprints, typically using databases of known spectra.
Ideally you would use a Raman instrument with high spectral resolution across the whole Raman range. This gives you better chemical specificity. You can then identify, differentiate and investigate a wider range of materials.
Quantification of material composition and properties
You can study changes in the details of the spectrum—such as the height, width, and position of the Raman bands—and determine things like:
- the relative amount of material
- layer thickness - from monolayer up to hundreds of nanometers
- whether it is under compression or tension
Differentiation of materials
You can determine if materials are the same or different by comparing their Raman spectra. A high spectral resolution system, such as Renishaw's inVia confocal Raman microscope enables you to distinguish even very similar crystal forms (polymorphic) of the same chemical.
