Application of laser Raman spectroscopic parameters of coal maceral analysis with different maturity

Shiyou shiyan dizhi, 2022
Laser Raman spectroscopy has shown a good application prospect for maceral analysis. Raman spectroscopic analysis of different macerals (e.g., vitrinite, semifusinite and macrinite) in coal samples with different maturity (%Ro=0.49%-1.88%) was carried ...

Raman Spectrum of Graphene and Graphene Layers [PDF]

Physical Review Letters, 2006
Graphene is the two-dimensional building block for carbon allotropes of every other dimensionality. We show that its electronic structure is captured in its Raman spectrum that clearly evolves with the number of layers. The D peak second order changes in shape, width, and position for an increasing number of layers, reflecting the change in the ...
