Raman Spectroscopy quotes

When he was offered a toast during the Nobel function being a strict abstains completely from alcoholic beverages he responded: Sir, you have seen the Raman effect on alcohol; please do not try to see the alcohol effect on Raman. Raman was a great lover of music. He used to say: I should live long, […]

Advantages and disadvantages of Raman Spectroscopy

Advantages of Raman Spectroscopy many organic and inorganic materials are suitable for Raman analysis. These can be solids, liquids, polymers or vapors. no sample preparation needed. not interfered by water. non-destructive. highly specific like a chemical fingerprint of a material. Raman spectra are acquired quickly within seconds. samples can be analyzed through glass or a […]

Molecular vibrations

Number and symmetry of vibrations With any molecule, the energy can be divided into translational energy, vibrational energy and rotational energy. Translational energy can be described in terms of three vectors 90° to each other and so has three degrees of freedom. Rotational energy for most molecules can also be described in terms of three […]

Quantum and Classical Raman theory

Quantum theory When light interacts with matter, the photons which make up the light may be absorbed or scattered, or may not interact with the material and may pass straight through it (Smith and Dent, 2005). When monochromatic light interacts with molecules, most of the photons are scattered without any change in energy. This process […]

Introduction in Raman Spectroscopy

A large variety of spectroscopic techniques are available for the analysis of materials and chemicals. Among these is Raman spectroscopy. Raman spectroscopy is based on the Raman effect which has been discovered by experiments of Sir C. V. Raman in 1928. In 1930, Sir Raman received the Nobel price for this discovery. This relies on […]
