National Science Day is held to commemorate On February 28 , 1928 in India for Sir CV Raman was awarded the Nobel Prize for his excellent discovery of the radiation effect scattering in physics called Raman Effect .

What is Raman Effect : As a result of Raman, a change in the length of light that occurs when a beam of light is distorted by molecules. When a beam of light cuts off a dust-free, transparent sample of a chemical computer, a small fraction of light appears on the sides other than that of the (incoming) incident. Most of this diffused light is constant. A small part, however, has a different wavelength of radiation than that of incident light; its presence is a result of the effect of Ramadan.

Raman effect

The practice is named after the Indian philosopher Sir Chandrasekhara Venkata Raman ( Full Name Of CV Raman ) , who began publishing the observation of the result in 1928. Landsberg; however, they did not publish their results until months after Raman.)

Raman scattering is probably easier to understand when the light of an event is considered to contain particles, or photons (with equal force), striking the molecules of the sample. Many bonds are stretched, and photons are dispersed with constant force and frequency. Sometimes, however, the molecule absorbs or activates photons, thus dispersing with reduced or elevated energy, and therefore at lower or higher levels. The frequency change is thus a measure of the amount of energy involved in the transition between the initial and final conditions of a dispersed molecule.

What is Raman effect

The effect of Raman is weak; made up of liquid the intensity of the affected light can be only 1 / 100,000 of that incident pole. The Raman line pattern is a feature of certain cell types, and its strength is equal to the number of molecules dispersed in the path of light. Therefore, the Raman spectra is used for quality and quantitative analysis.

The force associated with changes in the Raman frequency is found to be the force associated with the changes between the various rotation and vibration conditions of the dispersing molecule. Pure circulation changes are small and difficult to detect, except for those of simple gas molecules. In the liquid, the circular motion is disturbed, and the rotating lines of the Raman are not found. Much of Raman’s work is concerned with the vibration change, which provides large visible shifts for gases, liquids, and durability. Gases with low cellular pressure at normal pressures therefore produce the worst effects of Raman; therefore fluidity and firmness are studied frequently.
