FUNCTION :
Raman spectroscopy is a non-destructive chemical analysis technique, which provides detailed information about chemical structure, phase and polymorphism, crystallinity and molecular interactions. It is based on the interaction of light with the chemical bonds within a material.
Raman is a light scattering technique, whereby a molecule scatters incident light from a light source. Most of the scattered light is at the same wavelength (or color) as the incident light source (likely a laser), and does not provide useful information – this is called Rayleigh Scatter. However, a small amount of light (typically 0.0000001%) is scattered at different wavelengths (or colors), which depend on the chemical structure of the sample under study – this is called Raman Scatter.
A Raman spectrum features a number of peaks, showing the intensity and wavelength position of the Raman scattered light. Each peak corresponds to a specific molecular bond vibration, including individual bonds such as C-C, C=C, N-O, C-H, etc., and groups of bonds such as benzene ring breathing mode, polymer chain vibrations, lattice modes, etc.
Information provided by Raman spectroscopy:
Raman spectroscopy probes a material and provides information about its:
• Chemical structure and identity
• Phase and polymorphism
• Intrinsic stress/strain
• Contamination and impurities
Types of samples analyzed with Raman:
In general, Raman spectroscopy is suitable for analysis of:
• Solids, powders, liquids, gels, slurries and gases
• Inorganic, organic and biological materials
• Pure chemicals, mixtures and solutions
• Metallic oxides and corrosion.
Common applications of Raman spectroscopy:
Raman spectroscopy is used in many varied fields – in fact, it can be used in any application where non-destructive, microscopic, chemical analysis and imaging is required. Whether the goal is qualitative or quantitative data, Raman analysis can provide key information easily and quickly. It can be used to rapidly characterize the chemical composition and structure of a sample, whether solid, liquid, gas, gel, slurry or powder.
