Iron chelation by the powerful antioxidant flavonoid quercetin.
Chelation of the bare and hydrated iron(II) cation by quercetin has been investigated at the DF/B3LYP level in the gas phase. Several complexed species arising from neutral and anionic forms of theExpand

DFT spin-orbit coupling between singlet and triplet excited states: A case of psoralen compounds
We present a computational protocol in which our method is used to compute spin–orbit (SO) matrix elements on time-dependent-density functional theory (TD-DFT). These SO contributions, computedExpand

A Theoretical Study of Brominated Porphycenes: Electronic Spectra and Intersystem Spin-Orbit Coupling.
In this paper, a time-dependent density functional theoretical study (TDDFT) has been carried out for brominated 2,7,12,17-tetra-n-propylporphycenes. Their potential therapeutic use in photodynamicExpand

Hydration of ionic species studied by the reference interaction site model with a repulsive bridge correction
We have tested the reference interaction site model (RISM) and the partially linearized hypernetted chain (PLHNC) closures improved by a repulsive bridge correction (RBC) for ionic hydrated species. Expand
