A theoretical and experimental study to unequivocal structural assignment of tetrahydroquinoline derivatives
(2013-06-24)
The tetrahydroquinoline derivatives can be easily synthesized through Povarov reaction and have several important biological activities. This work describes a comparative study for the unequivocal assignment of molecular ...
Multivariate calibrations on H-1 NMR profiles for prediction of physicochemical parameters of Brazilian commercial gasoline
(Elsevier B.V., 2012-09-01)
Brazilian commercial gasoline follows a rigid quality control, covered by Regulation ANP 309 and following international analytical protocols, such as ASTM and ABNT. Each property is a complicated function of the gasoline ...

(1)H NMR Fingerprinting of Brazilian Commercial Gasoline: Pattern-Recognition Analyses for Origin Authentication Purposes
(Amer Chemical Soc, 2009-08-01)
In (his work, the combination of hydrogen nuclear magnetic resonance ((1)H NMR) fingerprinting of gasoline with pattern-recognition analyses provides an approach to distinguish Brazilian commercial gasoline, processed in ...
NMR study of styrene-butadiene rubber (SBR) and TiO2 nanocomposites
(Elsevier B.V., 2009-08-01)
The chemical behavior of styrene-butadiene rubber (SBR) and of the SBR/TiO2 and photodegraded SBR/TiO2 nanocomposites was investigated through nuclear magnetic resonance spectroscopy (NMR) in the solid state with magic ...
