THE RAMAN SPECTRUM OF GYPSUM [PDF]
Proceedings of the National Academy of Sciences, 1929 In an investigation of the Raman spectra of some ionized substances in aqueous solution, it was found [1] that the frequency shift given by a solution of potassium carbonate was in fairly close agreement with the strongest shift given by calcite. Data for such a comparison in other cases do not appear to exist, for change of frequency on scattering has

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 ...

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 ...
