Solving Vibronic Dynamics in Electron Continuum

M Ćosićová, J Dvořák, M Čížek - Journal of Chemical Theory …, 2024 - ACS Publications
We present a general two-dimensional model of conical intersection between metastable
states that are vibronically coupled not only directly but also indirectly through a virtual …

Contrasting Dynamics in Isoelectronic Anions Formed by Electron Attachment

P Nag, M Ranković, M Polášek… - The Journal of …, 2024 - ACS Publications
Cyanogen NCCN and cyanoacetylene HCCCN are isoelectronic molecules, and as such,
they have many similar properties. We focus on the bond cleavage in these induced by the …

Signatures of s-wave scattering in bound electronic states

RE Moorby, V Parravicini, M Alessio… - Physical Chemistry …, 2024 - pubs.rsc.org
We compute EOM-EA-CCSD and EOM-EA-CCSDT potential energy curves and one-
electron properties of several anions at bond lengths close to where these states become …

Electron-impact vibrational excitation of isocyanic acid HNCO

RK TP, P Nag, M Ranković, R Čurík, A Knížek, S Civiš… - Physical Review A, 2020 - APS
In a combined experimental and theoretical study, we probe the vibrational excitation of
isocyanic acid induced by electron impact in the energy range up to 5 eV. Experimentally …

Computing resonance energies directly: method comparison for a model potential

JU Davis, T Sommerfeld - The European Physical Journal D, 2021 - Springer
In contrast to bound states, electronically metastable states or resonances still represent a
major challenge for quantum chemistry and molecular physics. The reason lies in the …
