Answer to Question #116509 in Physics for Nimra kanwal

Question

What information we get from Raman spectra?

Answer 1

Raman spectroscopy probes the chemical structure of a material and provides information about:

• Chemical structure and identity
• Phase and polymorphism
• Intrinsic stress/strain
• Contamination and impurity

Typically a Raman spectrum is a distinct chemical fingerprint for a particular molecule or material, and can be used to very quickly identify the material, or distinguish it from others. Raman spectral libraries are often used for identification of a material based on its Raman spectrum – libraries containing thousands of Raman spectra are rapidly searched to find a match with the spectrum of the analyte.
