Nucleophilic Substitution (SN2): Dependence on Nucleophile, Leaving Group, Central Atom, Substituents, and Solvent

TA Hamlin, M Swart, FM Bickelhaupt - ChemPhysChem, 2018 - Wiley Online Library
The reaction potential energy surface (PES), and thus the mechanism of bimolecular
nucleophilic substitution (SN2), depends profoundly on the nature of the nucleophile and …

Accurate spin-state energies for iron complexes

M Swart - Journal of chemical theory and computation, 2008 - ACS Publications
A critical assessment of the OPBE functional is made for its performance for the geometries

Telomere structure and stability: covalency in hydrogen bonds, not resonance assistance, causes cooperativity in guanine quartets

C Fonseca Guerra, H Zijlstra, G Paragi… - … A European Journal, 2011 - Wiley Online Library
We show that the cooperative reinforcement between hydrogen bonds in guanine quartets is
not caused by resonance‐assisted hydrogen bonding (RAHB). This follows from extensive …

Importance of the basis set for the spin-state energetics of iron complexes

M Güell, JM Luis, M Sola, M Swart - The Journal of Physical …, 2008 - ACS Publications
We have performed a systematic investigation of the influence of the basis set on relative
spin-state energies for a number of iron compounds. In principle, with an infinitely large …

Adenine versus guanine quartets in aqueous solution: dispersion-corrected DFT study on the differences in π-stacking and hydrogen-bonding behavior
