Before describing how the
Raman effect arises, it is necessary to
Thursday's Google doodle features a postage stamp like graphic with Sir CV Raman's head shot along with the diagram of the apparatus demonstrating the
Raman effect. Raman was born in Thiruvanaikaval, Trichinopoly, on November 7, 1888.
The doodle displays CV Raman's full face behind the letter G and adjacent to it shows the
Raman effect with light rays emitting from a source.
Although the
Raman effect is well known to physicists it has not been involved in laser action.
The underlying principle of the
Raman effect can be explained through quantum mechanics.
National Science Day is celebrated to honour our Nobel laureate Sir Chandrasekhara Venkata Raman for his invention of the
Raman effect through his experiments on the scattering of light.
You will also learn that the bluish discoloration of the parietal layer of the tunica vaginalis is due to the
Raman effect, another patriotic chestnut.
Raman effect was discovered almost one hundred years ago.
Detecting these rare photons is the challenge--and ultimately the payoff--for scientists seeking to harness the
Raman effect for clinical applications.
According to Dr Castanon, the pounds 600,000 project exploits a natural phenomena called the
Raman effect that affects light passing through a material.
Now, Dr Juan Diego Ania-Castauun and his colleagues have used a special process called the
Raman effect to transform a long optical fibre into an ultra-long laser.
Gregoriou (Foundation of Research and Technology-Hellas, Greece) and Braiman (a physicist at Syracuse U., US) have asked their contributors--specialists in the use of the
Raman effect for characterizing polymers and biological systems--to address selected areas of interest in applications of infrared and Raman techniques.
