Journal ArticleDOI
Revision of the thermodynamics of the proton in gas phase.
TL;DR: Although the proton behaves as a classical particle at high temperatures, it is strongly recommend the use of quantum results at all temperatures, for the integrated heat capacity and the Gibbs free energy change.
Journal ArticleDOI
Solvent effects on the antioxidant activity of 3,4-dihydroxyphenylpyruvic acid : DFT and TD-DFT studies
Jean Jules Fifen,Jean Jules Fifen,Mama Nsangou,Mama Nsangou,Zoubeida Dhaouadi,Ousmanou Motapon,Nejm-Eddine Jaidane +6 more
TL;DR: In this paper, the antioxidant activity of 3,4-dihydroxyphenylpyruvic acid (3-4-DHPPA) was investigated using B3LYP/6-31+G*, 6-311++G** and Integral Equation Formalism Polarizable Continuum Model (PCM) methods.
Journal ArticleDOI
Solvation Energies of the Proton in Methanol.
Jean Jules Fifen,Jean Jules Fifen,Mama Nsangou,Mama Nsangou,Zoubeida Dhaouadi,Ousmanou Motapon,Nejm-Eddine Jaidane +6 more
TL;DR: The thermochemistry of the solvation of the proton in methanol within the cluster-continuum model is investigated and it comes out that the functional M062X is better than B3LYP, on the evaluation of gas phase clustering energies of protonated meethanol clusters.
Journal ArticleDOI
Vibrational analysis of amino acids and short peptides in hydrated media. IV. Amino acids with hydrophobic side chains: L-alanine, L-valine, and L-isoleucine.
TL;DR: The number of hydration considered in the present report is justified due to the opportunity to analyze the vibrational features of these amino acids in hydrated media by means of the density functional theory (DFT) calculations at the B3LYP/6-31++G* level.
Journal ArticleDOI
DFT study of the reaction of quercetin with ·O2- and ·OH radicals
TL;DR: In this paper, the interaction of one of the most reactive flavonoid quercetin with two ROS: hydroxyl radical ( · OH ) and superoxide radical ( O 2 - ) using B3LYP/6-31++G* level of theory was studied.
