The Raman effect is based on light scattering. In most instances, light that “hits” a molecule does not interact with it and so the photon does not lose energy. This process is known as elastic ...

Raman spectroscopy is a non-destructive analytical method that generates complex information about the phase, chemical structure and crystallinity of sample matter. A range of molecular interactions ...

Raman spectroscopy is a highly efficient technique used to identify chemicals. While the Raman Effect has been known for almost 100 years, recent developments have enabled Raman spectrometers to be ...

Raman spectroscopy is an analytical characterization technique which has been around for many decades. Since it’s first inception to build a database of molecular vibrational frequencies, it has ...

Engineers at Johns Hopkins University say they are using a non-invasive optical probe to understand the complex changes in tumors after immunotherapy. Their method combines detailed mapping of the ...

Raman spectroscopy has been highlighted as a vital tool for characterizing 2D materials-based van der Waal heterostructures. In this article, we explore its applications in analyzing graphene, TMDs ...

A team led by Prof. DONG Chunhua from the University of Science and Technology of China (USTC), in collaboration with Prof. BO Fang's group from Nankai University, has successfully developed a ...

Laser wavelength selection, a critical determinant of accuracy and data quality, is guided by factors such as resonance, fluorescence, and sample absorption. Ensuring the correct laser wavelength ...
