Semiempirical Quantum-Chemical Orthogonalization-Corrected Methods: Benchmarks of Electronically Excited States.
The semiempirical orthogonalization-corrected OMx methods have recently been shown to perform well in extensive ground-state benchmarks. They can also be applied to the computation of electronically excited states when combined with a suitable multireference configuration interaction (MRCI) treatment. We report on a comprehensive evaluation of the performance of the OMx/MRCI methods for electro...

Semiempirical orthogonalization-corrected methods (OM1, OM2, and OM3) go beyond the standard MNDO model by explicitly including additional interactions into the Fock matrix in an approximate manner (Pauli repulsion, penetration effects, and core-valence interactions), which yields systematic improvements both for ground-state and excited-state properties. In this Article, we describe the underl...
متن کاملSemiempirical Quantum-Chemical Orthogonalization-Corrected Methods: Benchmarks for Ground-State Properties
The semiempirical orthogonalization-corrected OMx methods (OM1, OM2, and OM3) go beyond the standard MNDO model by including additional interactions in the electronic structure calculation. When augmented with empirical dispersion corrections, the resulting OMx-Dn approaches offer a fast and robust treatment of noncovalent interactions. Here we evaluate the performance of the OMx and OMx-Dn met...
متن کاملBenchmarks for electronically excited states: CASPT2, CC2, CCSD, and CC3.
A benchmark set of 28 medium-sized organic molecules is assembled that covers the most important classes of chromophores including polyenes and other unsaturated aliphatic compounds, aromatic hydrocarbons, heterocycles, carbonyl compounds, and nucleobases. Vertical excitation energies and one-electron properties are computed for the valence excited states of these molecules using both multiconf...
متن کاملElectronically Excited States of Interstellar Anions
In the search for carriers of the diffuse interstellar bands (DIBs), a nearly ubiquitous, as-of-yet unattributed interstellar absorption spectrum, new theories are being proffered to explain this astronomical phenomenon. One of these is that rarely occurring excited states of anions may be responsible for some of these features. Using state-of-the-art quantum chemical techniques we examine near...
