Raman spectroscopy is a form of vibrational spectroscopy that is used to observe changes in a molecule; these may be rotational, vibrational or some other form. It helps to understand the ...

A SYSTEMATIC investigation at low temperatures of the oscillation and rotation Raman spectra of simple molecules as they are affected by their state of aggregation and by temperature seems to us of ...

Semiconductor nanocrystals are conducting materials with a size that has been reduced to the nanoscale. This size reduction can greatly enhance the physical, chemical, and optical characteristics, ...

Raman spectroscopy is a molecular spectroscopy, which is observed as inelastically scattered light and enables the interrogation and identification of vibrational (phonon) states of molecules.

(a) Schematic diagram of the pump burst and the Stokes burst in the time domain. N: number of pulses in burst. ∆τ: inter-pulse temporal separation. φ: pulse-to-pulse offset phase. Ω R: Raman frequency ...

Spectroscopy is an analytical technique that measures the interaction between electromagnetic radiation (or other energetic probes, such as electrons or ions) and matter as a function of wavelength, ...

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 ...

Law enforcement personnel, laboratory technicians, crime scene investigators and many others face a significant challenge for identification of materials in a forensic investigation. During an ...

Polymer extrusion transforms materials, optimizing properties through real-time Raman spectroscopy and PCA for enhanced ...

Like infrared (IR) spectroscopy, Raman spectroscopy is a type of vibrational spectroscopy. These similar methods have some differing qualities, as IR bands emerge due to alterations in the dipole ...
