Inertia defects of urea
(1986)
By means of an iterative consistency method it has been determined a complete potential field for the urea molecule. The force constants set which interpretates well the vibrational spectra of urea and its deutero derivatives ...
Vibrational spectra and normal coordinate analysis of diamminemercury(II) chloride with 14N/15N and H/D isotopic substitution
(1981)
The IR and Raman spectra of solid diamminemercury(II) chloride with 14N/15N and H/D isotopic substitution have been measured. The spectra have been interpreted assuming D3d symmetry for the [Hg(NH3)2]2+ cations which have ...
Experimental and chemometric strategies for the development of Green Analytical Chemistry (GAC) spectroscopic methods for the determination of organic pollutants in natural waters
(Elsevier Science, 2016-12)
The development of Green Analytical Chemistry (GAC) methods is one of the most active areas of Green Chemistry. Especially relevant are GAC methods devoted to the detection and quantification of environmental pollutants, ...

(Soc Brasileira QuimicaSao PauloBrasil, 2006)
Excitation-emission fluorescence spectroscopic analysis in the presence of interferents. A laboratory experiment integrating analytical chemistry and advanced data processing
(The Chemical Educator, 2013-05)
In the present report an advanced experiment is described to introduce chemistry students to the direct chemometric resolution of binary mixtures of two pharmaceuticals (oxatomide and phenylephrine) by measuring ...
USING SPREADSHEET SOFTWARE AS A TEACHING TOOL IN QUALITATIVE ANALYTICAL CHEMISTRY
(Soc Brasileira Quimica, 2016-04-01)
The use of spreadsheet softwares is not widespread in Chemical Education in Brazil as a computational education tool. By its turn the Qualitative Analytical Chemistry is considered a discipline with classical and non-flexible ...
