Electromagnetic Spectrum– Regions of interest to the Chemical Spectroscopist
Electromagnetic radiation is radiant energy that is transmitted through space at the speed of light. Humans can experience it in the form of light and…
What factors contribute to deviations from the Beer-Lambert’s Absorbance law?
Beer–Lambert’s Absorbance law is a universally accepted relationship which helps calculation of concentration of an absorbing species from measured absorbance values. Under ideal conditions absorbance…
Scope of applications of Raman Spectroscopy
拉曼光谱提供了several advantages over IR spectroscopy which can be summarized as: Non – destructive and requiring no sample preparation Convenience of handling aqueous…
Approaches for the enhancement of Raman spectral lines in Raman Spectroscopy
As you would be aware a very small fraction (1 in ) of scattered radiation is available for Raman activity. This was the main impediment…
What are the basics of Raman Spectroscopic transitions?
Light passing through an optically transparent medium undergoes several physical changes due to its interaction with the particles constituting the media. Scattering takes place when the…
