What is Raman Spectroscopy? Raman effect is first discovered by C.V. Raman and K.S Krishan in 1928. When a sample exposes monochromatic light, the sample absorbs the light, visual portion of light gets transmitted to the sample. However, a minor part of the light is scattered by the sample in all direction. Incident light has a particular frequency, if scattering light has frequency same as incident light, the scattering is called Rayleigh scattering. It has been observed that about 1% of total scatter intensity occurs frequency different from incident frequency, this is called Raman scattering. Raman scattering can be called a two photon process, an electron has different vibrational levels, they are defined by different specific energy differences.
When an incident molecular light interacts with an electron in the sample, an electron absorbs energy from an incident photon. It strikes the state of virtual energy, the energy transform is given by a formula. the electron falls back to energy level by losing energy. If energy loss equals the energy of the incident photon. An electron falls back to an initial level, and if this process emits another photon, since the energy loss equal value same frequency of the incident photon, as the frequency is same, Rayleigh scattering occurs. However, sometimes electron loss energy from virtual state to fall back to different vibration level. In this case, energy loss by the electron is different, and the energy absorbed from incident photon, as a result, photon emitted, the photon has energy different from incident photon, it's possible when the frequency of emitted photon is different from the frequency of incident photon, this gives right to Raman scattering, depends on final energy of electron or final vibrational of electron, Raman scattering can be separated into two, stock lines and anti-stocks lines.
If the frequency of scattering photon less than the frequency of the incident photon, stocks lines is observed on Raman spectra. It happens when an electron absorbs energy, Similarly, If frequency If scattering photon greater than the frequency of the incident photon, anti-stocks lines is observed, this means the energy released by the electron.
Raman spectra give a molecular fingerprint, different molecules have different Raman spectra, By studying spectra, one can identify rotational levels and, it helps to perform analysis of qualitative, similarly, the intensity of particular Raman lines help determine the concentration of molecule in a sample, In this manner, quantitive analysis can be done. Thus Raman spectroscopy can be used as both qualitative and quantitative analysis tool. Raman Instrument has a complete line of handheld Raman Analyzer, Portable Raman Spectrometer, Raman Microscope, Educational Raman System etc.
What is working principle of Raman spectroscopy?
Ramn spectroscopy analysis on a given sample understand is exposed and visible region absorbs light. A major portion of the light gets transmitted to the sample. A lot of the light is scattered by the sample in all directions. One can observe the scattering at right angle to the incident has a particular frequency. If the scattered light has the frequency, same as the incident light, then the scattering is called as rayleigh scattering. However, it has been observed that about 1% of the total scattered intensity frequency is different from the incident frequency. This is called as Raman category. Scattering can be thought of as two photon process. Electrons have different vibration levels. They are defined by specific energy differences. When an incident like interacts with the electron in the sample, the electron absorbs energy from the incident photon and dresses over to the state of energy. The energy transferred is given by the formula new when you the frequency of incident photon then falls back by losing energy. If the energy lost equals the energy of the incident photon, the electron falls back to its initial level and in this process, and the photon is equivalent to the energy of incident photon. The photon has the same frequency as the incident photon. As the frequencies seem really scattering occurs, however, sometimes electrons. We're losing energy from the virtual state can fall back to a different vibration level. In this case, energy lost by the electron. And the energy absorb of the incident photon. As a result, the photon emitted by the electron has energy as possible currency of the hold on , depending upon the final energy of the electron. Our final vibration can be separated into stokes line, an anti stokes line is less than the frequency. Stokes lines are observed on Raman spectrum. This happens when the electron absorbs energy frequency of the emitted photon is greater than incident photon. And the stock lines are observed. This means that energy is released by the electron spectra, the molecular fingerprint. It is different for different molecules. By studying the spectra, one can identify the traditional levels. And that's a particular molecule in performing data analysis. Similarly, the intensity of a particular online heads. One determine the concentration of molecules in a sample in this manner, quantitative analysis can be done, does Raman spectroscopy can be used to perform the analysis on the sample.

Q: How is the Raman spectroscopy technology is discovered?
Q: How is the Raman spectroscopy technology is discovered?
A: There is a very interesting story told in 1920s, an Indian scientist named Raman discover why the sea is so blue, whose blue brighter than blue sky, and after his research, he finally found in 1928 that the sea has absorbed uv range and generated new blue lights. Raman write a paper of his discovery, in order to remember Raman scientist great discovery and people use his name to describe this phenomenon Raman Spectroscopy. The first Discovery of Raman spectroscopy in 1928. And in 1930s, Raman scientist has won the Nobel prize. In the scientists history, Raman spectroscopy has been a very big discovery.
Q: What is the Raman spectroscopy working principle?
A: When the molecule absorbs laser energy and generate energy level shift, but it is an unstable state. It can ring-down to the original energy level. If no energy shift part called Rayleigh scattering. However some part shift from E0 to E2, fall down to E1, This situation is called STOCKS, a single photon energy is lower energy & frequency than the laser energy but longer wavelength. The other part from E1 to higher energy level E1+hv0, and its ring down to E0 with the higher frequency and energy, but shorter wavelength called anti-stokes lines. In these situations still ring down to the deeper energy levels but less. Raman spectroscopy are mainly analyzing the STOKES lines.
Q: How is the Raman spectrometer work?
A: First of all, the narrow linewidth laser generates an excitation light go through the fiber and collimator mirror to form a parallel incident light, excitation light focus from here, and shoot on the sample to be detected. The sample absorbs excitation light energy and it happens the energy levels shift, then go through ring-down process of generating new Raman light with a 360 degree scattering. Some portions of Raman scattering can be collected by our objective lens, then reflected from here, through long pass filter Rayleigh scattering, then couple into inside fiber and spectrometer. Raman spectrometer is used to analyze the collected Raman signal, wavelength, and intensity. Finally, it can get the Raman signal.
