Definition:Raman Spectroscopy is a sophisticated analytical technique used to observe vibrational, rotational, and other low-frequency modes in a system. This material characterization technique ...

During light scattering, the majority of scattered light undergoes no change in frequency (or energy), in a process referred to as referred to as elastic or Rayleigh scattering. Raman spectroscopy ...

Within the chemical industry, the manufacturing of polymers is one of the largest sectors - the volumes of polystyrene alone produced annually worldwide reaching billions of kilograms. 1 ...

The data obtained helps identify pigments, dyes, and paints, shedding light on when it was produced and its authenticity. Raman spectroscopy measures lower frequency vibrations and provides rich ...

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, ...

Spectral resolution is the most important feature of a spectrometer. This parameter determines the maximum number of spectral peaks that can be achieved using the system. For example, in the case of a ...

Graphene is a two-dimensional, one-atom-thick hexagonally organized material composed of sp2 carbon networks with strong covalent bonds. As graphene absorbs only 2.3 percent of incident light, it is ...

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 ...

(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 ...
