Global chemical reactivity parameters for several chiral beta-blockers from the Density Functional Theory viewpoint

open access: yesClujul Medical, 2016
Background and aim Beta-adrenergic antagonists have been established as first line treatment in the medical management of hypertension, acute coronary syndrome and other cardiovascular diseases, as well as for the prevention of initial episodes of ...

Quantum Indistinguishability in Chemical Reactions [PDF]

open access: yes, 2017
Quantum indistinguishability plays a crucial role in many low-energy physical phenomena, from quantum fluids to molecular spectroscopy. It is, however, typically ignored in most high temperature processes, particularly for ionic coordinates, implicitly ...

Rotation in attosecond vibronic coherence spectroscopy for molecules

open access: yesCommunications Physics
Excitation or ionization of a molecule by ultrafast laser pulses can create a superposition of electronic states, whose dynamics is influenced by the interplay of electronic coherence and nuclear motion, resulting in charge migration and possibly charge ...

Insights into enzymatic halogenation from computational studies [PDF]

open access: yes, 2014
The halogenases are a group of enzymes that have only come to the fore over the last 10 years thanks to the discovery and characterization of several novel representatives.

Global and local aromaticity of acenes from the information-theoretic approach in density functional reactivity theory.

open access: yesPhysical Chemistry, Chemical Physics - PCCP, 2019
In this work, we report a systematic study on the global and local aromaticity of acenes using a series of model structures from 2-acene to 11-acene.

Exploration of Reaction Pathways and Chemical Transformation Networks

open access: yes, 2018
For the investigation of chemical reaction networks, the identification of all relevant intermediates and elementary reactions is mandatory. Many algorithmic approaches exist that perform explorations efficiently and automatedly.

An Unstructured Mesh Convergent Reaction-Diffusion Master Equation for Reversible Reactions [PDF]

open access: yes, 2018
The convergent reaction-diffusion master equation (CRDME) was recently developed to provide a lattice particle-based stochastic reaction-diffusion model that is a convergent approximation in the lattice spacing to an underlying spatially-continuous ...

Spectroscopic Properties and Computational Studies of Phosphosilicate-Doped Compounds Including (F, Cl, Br) [PDF]

open access: yesJournal of Chemistry Letters
In this work, we added Cl, Br, and F atoms to the phosphate-silicate (PHS) molecule using the density functional theory (DFT) approach using a 6-31G basis set and the B3LYP level of theory.

Local Isoelectronic Reactivity of Solid Surfaces

open access: yes, 1996
The quantity w^N(r) = ( 1/ k^2 T_el)[partial n(r, T_el) / partial T_el]_(v(r),N) is introduced as a convenient measure of the local isoelectronic reactivity of surfaces.
