Raman spectroscopy is a spectroscopic technique typically used to determine vibrational modes of molecules, although rotational and other low-frequency modes of systems may also be observed. Raman spectroscopy is commonly used in chemistry to provide a structural fingerprint by which molecules can be identified.
Sir Chandrasekhara Venkata Raman was an Indian physicist known for his work in the field of light scattering. Using a spectrograph that he developed, he and his student K. S. Krishnan discovered that when light traverses a transparent material, the deflected light changes its wavelength and frequency. This phenomenon, a hitherto unknown type of scattering of light, which they called "modified scattering" was subsequently termed the Raman effect or Raman scattering. Raman received the 1930 Nobel Prize in Physics for the discovery and was the first Asian to receive a Nobel Prize in any branch of science.
Raman scattering or the Raman effect is the inelastic scattering of photons by matter, meaning that there is both an exchange of energy and a change in the light's direction. Typically this effect involves vibrational energy being gained by a molecule as incident photons from a visible laser are shifted to lower energy. This is called normal Stokes Raman scattering. The effect is exploited by chemists and physicists to gain information about materials for a variety of purposes by performing various forms of Raman spectroscopy. Many other variants of Raman spectroscopy allow rotational energy to be examined and electronic energy levels may be examined if an X-ray source is used in addition to other possibilities. More complex techniques involving pulsed lasers, multiple laser beams and so on are known.

Subramaniam, Subrahmanyam, Subramanyam or Subramanian is a South Indian male given name. Due to the South Indian tradition of using patronymic surnames it may also be a surname for males and females. The etymology of the name is from Sanskrit; however, a common translation is "dear to Brahmam", or "of good deeds". An alternative proposed translation is derived from merging two common Sanskrit words supri-ya, meaning "good" or "dear," and man-ya, meaning jewel; the name translates loosely as "worthy jewel". Subramaniam is one of the many names of the Hindu god Karthikeya, also known as Kumara or Murugan.
