RAMAN SPECTROSCOPY Meaning and
Definition
-
Raman spectroscopy is a powerful analytical technique used in the field of chemical and materials sciences for studying the molecular structure and identification of various substances. It is based on the Raman effect, which involves the interaction of light with matter to produce a scattered light with different frequencies.
In Raman spectroscopy, a sample is irradiated with monochromatic light, typically from a laser source, which excites the sample's molecules. The scattered light is then collected and analyzed for shifts in frequency, known as Raman shifts, which occur due to the vibrational and rotational energy states of the molecules. These shifts provide valuable information about the chemical composition, molecular structure, and bonding characteristics of the sample.
This technique offers several advantages over other spectroscopic techniques. It can be used for the analysis of solids, liquids, and gases, as well as for bulk and surface characterization. Raman spectroscopy is non-destructive, meaning the sample remains unaltered after analysis. It also requires minimal sample preparation and provides rapid and precise results. Additionally, Raman spectroscopy can be performed at ambient conditions or under extreme conditions, such as high temperatures and pressures, making it suitable for a wide range of applications in diverse fields.
Overall, Raman spectroscopy is an invaluable tool for chemical identification, material characterization, quality control, forensic analysis, and research in many scientific disciplines. Its ability to provide detailed molecular information makes it an essential technique for advancing knowledge and understanding in various areas of science and technology.

Etymology of RAMAN SPECTROSCOPY
The word "Raman Spectroscopy" is named after the Indian physicist Sir C.V. Raman, who discovered the Raman effect in 1928. Sir C.V. Raman was awarded the Nobel Prize in Physics in 1930 for this discovery. Raman spectroscopy refers to a technique that uses the Raman effect to analyze the interaction of light with a sample, providing information about its molecular composition and structure.
