The PM6-FGC Method: Improved Corrections for Amines and Amides
Molecules, 2022 Recently, we reported a new approach to develop pairwise analytical corrections to improve the description of noncovalent interactions, by approximate methods of electronic structures, such as semiempirical quantum mechanical (SQM) methods. In particular,

Resonant Ionic, Covalent Bond, and Steric Characteristics Present in 1Σu+ States of Li2
Molecules, 2022 The molecular bonding in the excited states of the alkali dimers involves the resonant ionic, covalent bond and steric interactions. We show here the case of the 1Σu+ states of Li2 by ab initio calculation.

Laser cooling and electronic structure studies of CaK and its ions CaK±
New Journal of Physics, 2021 Aiming at a laser cooling investigation, we have used ab initio complete active space self consistent field (CASSCF)/(MRCI +Q) calculations to study the electronic structure of the diatomic molecule CaK and its molecular ions CaK ^+ and CaK ^− .

Potential Energy Curves for CO [PDF]
The Journal of Chemical Physics, 1960 Potential energy curves for the X 1Σ+, a 3πr, a′ 3Σ+, d 3Δ, e 3Σ—, A 1π, and B 1Σ+ electronic states of the CO molecule have been calculated by the Rydberg-Klein-Rees method. The curve for the A 1π state will have to bend sharply in the range between 1.9 and 2.1 A or it will have to pass through a maximum to reach the proper dissociation limit.

Benchmark potential energy curve for collinear H3
Chemical Physics Letters, 2022 A benchmark-quality potential energy curve is reported for the H$_3$ system in collinear nuclear configurations. The electronic Schrödinger equation is solved using explicitly correlated Gaussian (ECG) basis functions using an optimized fragment initialization technique that significantly reduces the computational cost.
