RAMAN SPECTRA FROM ACETONE [PDF]

Proceedings of the National Academy of Sciences, 1929
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.

Raman Spectra of Deuteroethylenes [PDF]

Nature, 1937
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.

Classification of Various Marijuana Varieties by Raman Microscopy and Chemometrics

Toxics, 2022
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 ...
