Esquema para interpretação de espectros de substâncias orgânicas na região do infravermelho
(2004)
This article decribes a simple and systematic method to interpret an infrared spectrum using a flow chart to elucidate the structure of a simple organic compound. It is aimed at undergraduate courses of organic chemistry ...
Vibrational spectra of Cd2As2O7
(John Wiley & Sons Ltd, 2004-02)
The infrared and Raman spectra of Cd2As2O7, belonging to the thortveitite structural type, were recorded and are discussed on the basis of a factor group analysis and by comparisons with related compounds.
In silico methods in forensic science: Quantum chemistry and multivariate analysis applied to infrared spectra of new amphetamine- and cathinone-derived psychoactive substances
(Elsevier B.V., 2018-06-01)
Identifying new psychoactive substances in a reliable manner is an exciting idea in forensic science. In this work, we apply in silico methods to recognize classes of drugs. We calculate the infrared spectra of 21 pairs ...
Vibrational spectra of magnesium oxalates
(Elsevier Science, 2010-07-20)
The infrared and Raman spectra of anhydrous MgC2O4 as well as those of the two polymorphic forms of the dihydrated oxalate, α-MgC2O4·2H2O and β-MgC 2O4·2H2O, were recorded and discussed on the basis of their structural ...
Vibrational spectra of the two hydrates of strontium oxalate
(Pergamon-Elsevier Science Ltd, 2015-02)
The infrared and Raman spectra of the two hydrates of strontium oxalate, SrC2O4·H2O and SrC2O4·2H2O, were recorded and discussed on the basis of their structural peculiarities and in comparison with the spectra of the ...
Vibrational spectra of disodium-oxidovanadium(IV) disulfate
(Taylor & Francis, 2020-05-20)
Disodium-oxidovanadium(IV) disulfate, a new and interesting battery electrode material, is prepared by a new very simple, and easy synthetic procedure. Its infrared and Raman spectra were recorded and discussed on the basis ...
