A novel implementation of CCSD analytic gradients using Cholesky decomposition of the two-electron integrals and Abelian point-group symmetry
Luca Melega, Tommaso Nottoli, Jürgen Gauss +1
We present a novel and efficient implementation of coupled-cluster with singles and doubles (CCSD) analytic gradients that combines the Cholesky decomposition (CD) of electron-repu…

The QUEST Database of Highly-Accurate Excitation Energies
Pierre-François Loos, Martial Boggio-Pasqua, Aymeric Blondel +2
We report theoretical best estimates of vertical transition energies (VTEs) for a large number of excited states and molecules: the \textsc{quest} database. This database includes…
