Unexpected hydrogen dissociation in thymine: predictions from a novel coupled cluster theory
Eirik F. Kjønstad, O. Jonathan Fajen, Alexander C. Paul +6
The fate of thymine upon excitation by ultraviolet radiation has been the subject of intense debate over the past three decades. Today, it is widely believed that its ultrafast exc…
Electronic dynamics created at conical intersections and its dephasing in aqueous solution
Yi-Ping Chang, Tadas Balciunas, Zhong Yin +8
A dynamical rearrangement in the electronic structure of a molecule can be driven by different phenomena, including nuclear motion, electronic coherence or electron correlation. Re…
X-ray Absorption Spectra for Aqueous Ammonia and Ammonium: Quantum Mechanical versus Molecular Mechanical Embedding Schemes
Sarai Dery Folkestad, Alexander C. Paul, Regina Paul +4
The X-ray absorption (XA) spectra of aqueous ammonia and ammonium are computed using a combination of coupled cluster singles and doubles (CCSD) with different quantum mechanical a…
