What is Surface-Enhanced Raman Scattering (SERS)? Surface-enhanced Raman scattering (SERS) is a powerful analytical technique that significantly enhances the Raman scattering signal of molecules ...

Raman scattering and Fluorescence emission are two competing phenomena, which have similar origins. Generally, a laser photon bounces off a molecule and looses a certain amount of energy that allows ...

With the 2019 Nobel Prize for Physics due to be announced on Tuesday 8 October, Physics World journalists pick their favourite Nobel awards from the past. Here Anna Demming argues the case for the ...

A BOOK on the Raman effect, written from a physical point of view, has been badly needed for some time. Since the discovery of the effect in 1928, there have been several attempts to review and ...

Chandrasekhara Venkata Raman is considered as one of best physicists ever produced by India. Born on November 7, 1888, in Tamil Nadu's Tiruchirapalli, Raman is known for his work in the field of light ...

Raman spectroscopy can be described as a molecular type of spectroscopy which is capable of detecting and differentiating material’s unique fingerprint. Typical Raman applications are in chemistry.

For anisotropic crystals, it has been known for many years that the birefringence effect rising from anisotropic refractive index should be considered for angle-resolved polarized Raman (ARPR) ...

Raman spectroscopy is a diagnostic method that uses scattered light to assess a sample's vibrational energy modes. It takes advantage of a concept called the Raman effect, which happens when a ...

Spatially masked optical Kerr effect (SM-OKE) spectroscopy is a nonresonant femtosecond pump–probe technique capable of measuring isotropic contributions to the transient birefringence of molecular ...

Several bioimaging techniques are potentially able to image the metabolic process underway in living cells, but many of them have some inherent drawbacks, either in terms of their limited spatial ...
