The CH3CHOO ‘Criegee intermediate’ and its anion: isomers, infrared spectra, and W3-F12 energetics
For the CH3CHOO Criegee intermediates (ethanal-oxide) and analogous anions, we obtain heats of formations and electron affinities at CCSDT(Q)/CBS level of theory by means of the high-level W3-F12 thermochemical protocol. The electron affinities amount to 0.20 eV and 0.35 eV for the cis and trans isomer, respectively. Neutral cis and trans isomers are separated by 14.1 kJmol−1, the anions are al...
متن کاملBridging the gap between quantum Monte Carlo and F12-methods
Tensor product approximation of pair-correlation functions opens a new route from quantum Monte Carlo (QMC) to explicitly correlated F12 methods. Thereby one benefits from stochastic optimization techniques used in QMC to get optimal pair-correlation functions which typically recover more than 85 % of the total correlation energy. Our approach incorporates, in particular, core and core-valence ...
متن کاملThe MP2-F12 method in the TURBOMOLE program package
A detailed description of the explicitly correlated second-order Møller-Plesset perturbation theory (MP2-F12) method, as implemented in the TURBOMOLE program package, is presented. The TURBOMOLE implementation makes use of density fitting, which greatly reduces the prefactor for integral evaluation. Methods are available for the treatment of ground states of open- and closed-shell species, usin...
متن کاملExplicit correlation and intermolecular interactions: investigating carbon dioxide complexes with the CCSD(T)-F12 method.
We have optimized the lowest energy structures and calculated interaction energies for the CO(2)-Ar, CO(2)-N(2), CO(2)-CO, CO(2)-H(2)O, and CO(2)-NH(3) dimers with the recently developed explicitly correlated coupled cluster singles doubles and perturbative triples [CCSD(T)]-F12 methods and the associated VXZ-F12 (where X = D,T,Q) basis sets. For a given cardinal number, we find that results ob...
متن کاملVaccinia virus protein F12 associates with intracellular enveloped virions through an interaction with A36.
Vaccinia virus is the prototypical member of the family Poxviridae. Three morphologically distinct forms are produced during infection: intracellular mature virions (IMV), intracellular enveloped virions (IEV), and extracellular enveloped virions (EEV). Two viral proteins, F12 and A36, are found exclusively on IEV but not on IMV and EEV. Analysis of membranes from infected cells showed that F12...
