TL;DR: The chemical characterization of genuine and fake artesunate antimalarial tablets by portable Raman spectroscopy and validation by FT-Raman spectroscopic and ambient mass spectrometry are illustrated.
Journal ArticleDOI
Spectroscopic characterization of natural chrysotile
TL;DR: Chrysotile, a variety of serpentine mineral, was investigated by vibrational and magnetic resonance spectroscopic methods as mentioned in this paper, which showed that chrysotiles are made up of thin and flexible fibrils, classified as asbestos.

The infra-red spectra of layer silicates
V.C. Farmer,J.D. Russell +1 more
TL;DR: In this article, the effect of the deviation from hexagonal symmetry shown by the tetrahedral layers of dioctahedral minerals on their vibrations is theoretically analyzed, and shown to account for some of the principal differences between the spectra of diotheoric and trioctahedric layer silicates in the 1300 to 400 cm−1 region.

Raman spectroscopic characteristics of Mg-Fe-Ca pyroxenes
TL;DR: In this article, the Raman spectra of several compositions of (Mg, Fe, Ca)SiO3 pyroxenes were collected at ambient conditions and more than 10 Raman vibrational modes were observed for these pyroxene in the wavenumber range between 200 and 1200 cm−1.
