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 ...

The Interplay of Structure and Dynamics in the Raman Spectrum of Liquid Water over the Full Frequency and Temperature Range. [PDF]
Journal of Physical Chemistry Letters, 2017 While many vibrational Raman spectroscopy studies of liquid water have investigated the temperature dependence of the high-frequency O-H stretching region, few have analyzed the changes in the Raman spectrum as a function of temperature over the entire ...

Stimulated Raman lineshapes in the large light–matter interaction limit
Optical Materials: X, 2022 Stimulated Raman scattering (SRS) represents a powerful tool for accessing the vibrational properties of molecular compounds or solid state systems. From a spectroscopic perspective, SRS is able to capture Raman spectra free from incoherent background ...

Frequency shifts in stimulated Raman scattering [PDF]
, 1980 The nonresonant contributions to the nonlinear susceptibility χ(3) produce a frequency chirp during stimulated Raman scattering. In the case of transient stimulated Raman scattering, the spectrum of the generated Stokes pulse is found at higher ...

Journal de Physique, 1965 The Raman spectrum of ZnO single crystals has been studied at room and low temperatures. About fifteen Raman peaks have been observed between 50 and 1 200 cm-1. The infrared reflection and transmission [1] measurements have also been made in the region 250 cm-1 to 1 500 cm-1 . The wurtzite (C46υ) structure has nine optical branches.

High-Resolution Near-Field Raman Microscopy of Single-Walled Carbon Nanotubes [PDF]
, 2003 We present near-field Raman spectroscopy and imaging of single isolated single-walled carbon nanotubes with a spatial resolution of ≈25 nm. The near-field origin of the image contrast is confirmed by the measured dependence of the Raman scattering ...
