The Dalton quantum chemistry program system

Kestutis Aidas, +83 more
TL;DR: Dalton is a powerful general‐purpose program system for the study of molecular electronic structure at the Hartree–Fock, Kohn–Sham, multiconfigurational self‐consistent‐field, Møller–Plesset, configuration‐interaction, and coupled‐cluster levels of theory.
Journal ArticleDOI

Cooperativity in hydrogen-bonded interactions: ab initio and "atoms in molecules" analyses.

TL;DR: The H(2)CO...(HF)(n) complexes were investigated using the MP2 method and the following basis sets and it was found that the cooperativity effect enhances significantly the F-H...O hydrogen bond; in some of cases one can detect the covalent nature of hydrogen bonding.
Journal ArticleDOI

Linear scaling coupled cluster method with correlation energy based error control.

TL;DR: The determination of the orbital spaces for the small orbital fragments is black box in the sense that it does not depend on any user-provided molecular fragmentation, rather orbital spaces are carefully selected and extended during the calculation to give fragment energies of a specified precision.
Journal ArticleDOI

A Locality Analysis of the Divide-Expand-Consolidate Coupled Cluster Amplitude Equations.

TL;DR: The locality analysis shows that a CC calculation on a large molecular system may be carried out in terms of CC calculations on small orbital fragments of the total molecular system, where the sizes of the orbital fragment spaces are determined in a black box manner to ensure that the CC correlation energy is calculated to a preset energy threshold.
Journal ArticleDOI

Maximum locality in occupied and virtual orbital spaces using a least-change strategy

TL;DR: A new strategy is introduced for obtaining localized orthonormal Hartree-Fock (HF) orbitals where the underlying principle is to minimize the size of the transformation matrix from the atomic orbital basis to the HF optimized orbital basis.
