Introduction to Raman Theory

Raman spectroscopy analysis is used the Raman scattering and the characteristics of Raman spectroscopy to detect the properties of chemical molecules or research substances. You can quickly and efficiently distinguish each element. It can also analyze isomeric elements (such as Natural and synthetic diamonds).

Raman scattering (Raman effect):

Pulsed lasers, or multiple laser beams Light has a certain probability of being scattered by a material. When photons are scattered, most of them are elastically scattered (Rayleigh scattering), such that the scattered photons have the same energy (frequency, wavelength and color) as the incident photons but different direction. An smaller fraction of the scattered photons (approximately 1 in 10 million) can be scattered inelastically, with the scattered photons having an energy different (usually lower) from those of the incident photons—these are Raman scattered photons.

Raman spectroscopy:

The Raman spectra are generated due to the interaction of the photons and the specimen molecules and are collected using optical filters form the scattered light. The Raman spectra contain information about the chemical species, molecular structures, and the conformation of the materials and provide a “fingerprint” for their identification. Generally, in a Raman spectrum, the Raman intensity is plotted versus the Raman shift. The Raman shift is defined as the difference of frequencies between the Raman scattered and the incident light beam.

 

Applications

Semiconductor Industry

The capacity of the Raman microspectroscopy has been well exploited in the field of semiconducting materials. It can detect with no sample preparation micro-inhomogeneities in integrated circuits, defects in both optoelectronic, microelectronic and sensor devices, that are of special technological interest in connection with their possible influence on the device performance. The method also permits quantitative and nondestructive microanalysis of structures and electrical properties in semiconductors. These mainly include damage induced by ion implantation, strains in heterostructures, measurements of crystallographic orientations, polycrystalline grains size and free carriers concentration.(Learn more)

Basic Science

Raman spectroscopy is widely used in chemistry and physics. Because vibrational frequencies are specific to a molecule‘s chemical bonds and symmetry, Raman provides a fingerprint to identify molecules. Raman spectrometer is one of the most efficient methods in chemical and physics analysis, short analysis time, identify molecular structure and composition(Learn more)

Pharmaceutical

The quality of the medication is closely correlated with the quality of the raw material. In the source of the incoming inspection, it is extremely important to do a good job of checking. Most compounds such as sugars, organic solvents, starches and polymers, inorganic multi-atom salts, and most oxides have characteristic Raman spectra. Use the advantages of Raman analyzer detecting and the Raman spectroscopy database of drugs. The results can be classified immediately within one minute. In other words, it can quickly and indeed complete the incoming inspection. Raman can analyze most of the drugs directly, it’s a non-destructive test method, no need to do pretreatment.(Learn more)

Life Sciences

Raman spectroscopy can be used to obtain information regarding molecular composition of the sample with very high accuracy. Applications of Raman spectroscopy in the life sciences have included quantification of biomolecules, hyperspectral molecular imaging of cells and tissue, medical diagnosis, and others.(Learn more)
