Raman Spectra of Deuteroethylenes [PDF]
All the different ethylenes, have been prepared, their Raman spectra in the liquid state measured and classified. A comparison between experimental data and theoretical predictions permits an estimate of the order of magnitude of the anharmonicity.

Raman scattering spectra of amber [PDF]
The Raman spectra of amber (succinite) of different transparency levels of the Palmniken Deposit of Kaliningrad of Russia were obtained using the Fourier Transform–Raman spectroscopy method, which allows obtaining real and elemental compositions.

RAMAN SPECTRA FROM ACETONE [PDF]
Measurements of Raman spectra from acetone have been published in a recent paper [1]. These measurements were so interpreted that out of thirteen modified lines, twelve corresponded to frequencies of observed infra-red absorptions, the thirteenth lying outside the range of the infrared measurements.

Classification of Various Marijuana Varieties by Raman Microscopy and Chemometrics
The Raman analysis of marijuana is challenging because of the sample’s easy photo-degradation caused by the laser intensity. In this study, optimization of collection parameters and laser focusing on marijuana trichome heads allowed collecting Raman ...

Raman Spectroscopic Study of Five Typical Plasticizers Based on DFT and HF Theoretical Calculation
Phthalic acid esters (PAEs) are the most commonly used plasticizers, and long-term or high levels of exposure to PAEs have a huge potential risk to human health.

Isomorphic Substitution in Vanadinite [Pb5(VO4)3C1] - Raman Spectroscopic Study [PDF]
The Raman and infrared spectroscopy of three vanadinite [Pb5(VO4)Cl] specimens from three localities has been studied. Single crystal Raman spectra were obtained and the spectra were found to be both orientation and temperature dependent.

Raman spectra of zinc phthalocyanine monolayers adsorbed on glassy carbon and gold electrodes by application of a confocal Raman microspectrometer [PDF]
Raman spectra of zinc phthalocyanine monolayers, adsorbed on gold and on glassy carbon surfaces (electrodes), are presented. These spectra have been recorded with the electrodes inside and outside an electrochemical cell filled with an aqueous ...
