Wavefunction methods for noncovalent interactions

TL;DR: In this paper, a review of recent works in wavefunction-based quantum chemistry techniques aimed at greater accuracy and faster computations for non-covalent interactions is presented, and a variety of wavefunction methods with promise for noncovalant interactions, various approximations to speed up these methods, and recent advances in wave function-based symmetry-adapted perturbation theory, which provides not only interaction energies but also their decomposition into physically meaningful components.

New coupled-cluster methods with singles, doubles, and noniterative triples for high accuracy calculations of excited electronic states.

TL;DR: It is demonstrated that the CR-EOMCCSD(T) approaches provide a highly accurate description of excited states dominated by double excitations, excited states displaying a manifestly multireference character, and PESs of exciting states along bond breaking coordinates with the ease of the ground-state CCSD(T).

The equation of motion coupled‐cluster method. A systematic biorthogonal approach to molecular excitation energies, transition probabilities, and excited state properties

TL;DR: In this paper, a comprehensive overview of the equation of motion coupled-cluster (EOM•CC) method and its application to molecular systems is presented by exploiting the biorthogonal nature of the theory, it is shown that excited state properties and transition strengths can be evaluated via a generalized expectation value approach that incorporates both the bra and ket state wave functions.

A fast intrinsic localization procedure applicable for ab initio and semiempirical linear combination of atomic orbital wave functions

TL;DR: In this article, a new intrinsic localization algorithm based on a recently developed mathematical measure of localization is proposed, which is adaptable for both ab initio and semi-empirical methods, even in those cases where the exact form of the atomic basis functions is not defined.
