A combined strategy based on the computation of absorption energies, using the ZINDO/S semiempirical method, for a statistically relevant number of thermally sampled configurations extracted from QM/MM trajectories is used to establish a one-to-one corresp ...

Dispersion-corrected atom-centered; potentials (DCACPs) for the element phosphorus were generated and tested for the BLYP, BP, and PBE generalized gradient approximations of the exchange-correlation functional. The accuracy and transferability of the DCACP ...

Fragmentation of doubly charged biomolecules, uracil and amino acids, has been investigated using different ab inito Molecular Dynamics Methods. Time-Dependent Density Functional Theory Molecular Dynamics give a description of the non-adiabatic effects, th ...

Dye-sensitized solar cells have gained widespread attention in recent years because of their low production costs, ease of fabrication and tunable optical properties, such as colour and transparency. Here, we report a molecularly engineered porphyrin dye, ...

We derive a Bohmian trajectory-based quantum dynamics approach for the calculation of adiabatic and nonadiabatic quantum effects in ab initio on-the-fly molecular dynamics simulations. The method is designed for calculations in the full, unconstrained, pha ...

We present an Fe K alpha resonant inelastic X-ray scattering (RIXS) and X-ray emission (XES) study of ferrous and ferric hexacyanide dissolved in water and ethylene glycol. We observe that transitions below the absorption edge show that the solvent has a d ...

A new series of organometallic ruthenium(II)-arene compounds of the type RuCl2(η6-arene)(phosphine) (phosphine = 1,3,5-triaza-7-phosphaadamantane, PTA, and 3,7-diacetly-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane, DAPTA) with different ...

Recent advances in algorithms and computational hardware have enabled the calculation of excited states with time-dependent density functional theory (TDDFT) for large systems of O(1000) atoms. Unfortunately, the aqueous charge transfer problem in TDDFT (w ...

The advent of x-ray free electron lasers is providing new opportunities for probing the ultrafast excited state dynamics using structurally sensitive techniques. Herein we use excited state wavepacket dynamics of a prototypical Cu(I)-phenanthroline complex ...

We review our recent work on ab initio nonadiabatic molecular dynamics, based on linear-response timedependent density functional theory for the calculation of the nuclear forces, potential energy surfaces, and nonadiabatic couplings. Furthermore, we descr ...

The parameterisation of accurate and transferable repulsive potentials is a key ingredient for the self-consistent-charge density functional tight-binding method (SCC-DFTB). In the conventional parameterisation scheme the balanced description of different ...

The authors describe two different implementations of time-dependent d. functional theory (TDDFT) for use in excited state mol. dynamics simulations. One is based on the linear response formulation (LR-TDDFT), whereas the other uses a time propagation sche ...

The behavior toward oxygen sensing of nanocomposites made of the aluminum oxide-hydroxide nanostructured solid support (AP200/19) and neutral blue emitting cyclometalated iridium(III) complexes was studied. The results are compared with the same dyes immob ...

Microbial production of desired compounds provides an efficient framework for the development of renewable energy resources. To be competitive to traditional chemistry, one requirement is to utilize the full capacity of the microorganism to produce target ...

In this work, we present a complete derivation of the NonAdiabatic Bohmian DYnamics (NABDY) equations of motion. This approach naturally emerges from a transformation of the molecular time-dependent Schrodinger equation in the adiabatic representation of t ...

Biased Born-Oppenheimer molecular dynamics simulations are performed to compute redox potential and free energy curves for the redox half reaction Ag(+)-->Ag(2+)+e(-) in aqueous solution. The potential energy surfaces of reactant and product state are line ...

Two D−π−A dyes based on the dithieno[3,2-b:2′,3′-d]pyrrole π-bridge (DTP) were synthesized, characterized using UV−vis absorption spectroscopy and electrochemistry, modeled using quantum chemical calculations, and used as sensitizers in dye-sensitized sola ...

Nuclear quantum dynamics beyond the Born-Oppenheimer approximation is performed using quantum trajectories. Within the adiabatic representation of the electronic states, NABDY (NonAdiabatic Bohmian DYnamics) is used in combination with DFT and LR-TDDFT to ...
