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 ...

Raman Spectrum of Diamond [PDF]

Nature, 1930
In the course of an examination of the infra-red and ultra-violet regions of the spectrum of a large number of diamonds, we have come across one which, unlike the others, is transparent both at about 8μ, and also in the ultra-violet so far out as λ2300.

On the Raman spectrum of argon dimersa)

The Journal of Chemical Physics, 1979
The pressure broadening of the rotational Raman transitions of argon dimers is calculated, using the semiclassical method. Simple models to compute the line broadening of noble gas dimers are put forward. The predictions of these simple models are compared with the results of the full semiclassical calculation.
