Probing the vibration of atoms provides detailed information on local structure and bonding that define material properties.

THIS communication reports the experimental observation of optical Raman scattering from oxygen and nitrogen in the atmosphere using a pulsed nitrogen ultraviolet laser 1,2 as a light source. Previous ...

A research team led by Prof. Fang Yonghua from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences ...

New first-principles simulations reveal how metallic surfaces reshape nanoscale vibrational imaging, advancing the ...

As a probe of vibrational transitions, Raman scattering has made great progress since it was first discovered and is considered a phenomenon that has led to the development of various schemes and ...

Nonlinear Raman microscopy techniques, such as coherent anti-Stokes Raman scattering and stimulated Raman scattering, are widely used to provide chemical and spatial information. A third nonlinear ...

Yet, that does not get to the core of the actual difference between these two methods, and why SERS (surface-enhanced Raman scattering, or alternatively surface-enhanced Raman spectroscopy) is often ...

Raman scattering spectroscopy has been widely adopted as an analytical technique, thanks to its ability to detect characteristic spectral fingerprints for individual molecules. However, its ...

Raman imaging techniques are used to obtain information about the molecular vibrations and crystal structure of a sample. Image pixels are used to acquire a complete spectrum, which is subsequently ...

In confocal Raman microscopy, a Raman spectrometer is coupled to a standard optical microscope, which leads to a high magnification of the sample and subsequent Raman analysis. Combining Raman ...
