Classification of Various Marijuana Varieties by Raman Microscopy and Chemometrics

open access: yesToxics, 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 ...

RAMAN SPECTRA FROM ACETONE [PDF]

open access: yesProceedings 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.
