Plant Metabolomics Using NMR Spectroscopy
(2019-01-01)
The major goal in plant metabolomics is to study complex extracts for the purposes of metabolic exploration and natural products discovery. To achieve this goal, plant metabolomics relies on accurate and selective acquisition ...
Long-range J(CH) heteronuclear coupling constants in cyclopentane derivatives. Part II
(John Wiley & Sons LtdChichesterInglaterra, 2007)
Theoretical studies of 13C carbon-NMR and vibrational (IR and Raman) Spectroscopies of Mefenamic Acid Polymorphs.
(Instituto de Física da Universidade de São Paulo.São Paulo, 2014-05-21)
The two polymorphs of mefenamic acid (MEF) or 2-[(2,3-
(dimethylphenyl)amino] benzoic acid polymorphs (known as I and 11 forms)
were studied in the framework of density functional theory (DFn. The DFT
calculations were ...
Experimental NMR and MS study of benzoylguanidines. Investigation of E/Z isomerism
(2013-04-01)
Molecules containing the guanidinic nuclei possess several pharmacological applications, and knowing the preferred isomers of a potential drug is important to understand the way it operates pharmacologically. Benzoylguanidines ...
H-1 and C-13 NMR spectroscopy analysis of acetonides of D-glucitol derivatives
(John Wiley & Sons LtdW SussexInglaterra, 1999)
Determination of acid dissociation constants of anomers of amino sugars by 1H NMR spectroscopy
(Elsevier Science Publishers B. V., 1997)
Acid dissociation constants of α- and β-D-glucos-, mannos-, and galactos-ammonium ions have been determined from 1H NMR chemical shifts of the individual anomers in D2O. Values of pKa(D) for the α- and β-ammonium ions ...
Determination of saturates, aromatics and ethanol in Brazilian commercial gasoline with low olefin content using 1 H NMR spectroscopy
(2010-12-01)
In this work, a Hydrogen Nuclear Magnetic Resonance (1H NMR) method has been developed to determine aromatics and ethanol in Brazilian commercial gasoline with low olefin content. The proposed method involves subdividing ...
