THE RAMAN SPECTRUM OF GYPSUM [PDF]

open access: greenProceedings 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

The Raman Spectrum of Deuterium [PDF]

open access: greenThe Journal of Chemical Physics, 1935
A number of observers have studied the emission spectra of mixtures of hydrogen and deuterium. The Fulcher bands of HD and D2 have been photographed [1]. In the extreme untrlaviolet Jeppesen [2], and Beutler and Mie [3], have obtained emission spectra from hydrogen-deuterium mixtures and have ascribed several bands to HD.

Distributed Raman Spectrum Data Augmentation System Using Federated Learning with Deep Generative Models [PDF]

open access: yesSensors, 2022
Chemical agents are one of the major threats to soldiers in modern warfare, so it is so important to detect chemical agents rapidly and accurately on battlefields. Raman spectroscopy-based detectors are widely used but have many limitations.

Raman Spectrum of Diamond [PDF]

open access: yesNature, 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.

Deep convolutional neural networks for Raman spectrum recognition: a unified solution [PDF]

open access: greenIn Analysis, 2017
Machine learning methods have found many applications in Raman spectroscopy, especially for the identification of chemical species. However, almost all of these methods require non-trivial preprocessing such as baseline correction and/or PCA as an ...

Excitation energy dependent Raman spectrum of MoSe2. [PDF]

open access: yesSci Rep, 2015
Raman investigation of MoSe2 was carried out with eight different excitation energies. Seven peaks, including E1g, A1g, E2g1 and A2u2 peaks are observed in the range of 100–400 cm−1.
