RCCSD(T) and/or CASSCF/MRCI calculations have been carried out on the X̃(1)A' and Ã(1)A'' states of HSiCl employing basis sets of up to the aug-cc-pV5Z quality. Contributions from core correlation and extrapolation to the complete basis set limit were included...

Energies and structures in biradical chemistry from the parametric two-electron reduced-density matrix method: applications to the benzene and cyclobutadiene biradicals.

Phys Chem Chem Phys. 2015 May 21;17(19):12521-9. doi: 10.1039/c5cp01310k.

The treatment of biradical chemistry presents a challenge for electronic structure theory, especially single-reference methods, as it requires the description of varying degrees and kinds of electron correlation. In this work we assess the ability of the parametric two-electron...

Interaction potential and transport properties of NeO(+).

The results of both experimental and theoretical studies of the mobility of O(+) in Ne are reported. Errors in the experiments have been carefully assessed, allowing the obtained data to serve as stringent tests of the ab initio potentials....

Accurate potential energy curves for HeO-, NeO-, and ArO-: spectroscopy and transport coefficients.

PMID: 15836210
J Chem Phys. 2005 Mar 15;122(11):114302. doi: 10.1063/1.1861874.

We calculate accurate potential energy curves for HeO(-), NeO(-), and ArO(-), including the full counterpoise correction and allowing for spin-orbit effects. Comparison with previous curves is presented, where these are available. The three curves, (2)Sigma(12) (+), (2)Pi(12), and (2)Pi(32),...

Franck-Condon simulation of the single vibronic level emission spectra of HSiF and DSiF including anharmonicity.

The Journal of chemical physics

Mok DK, Lee EP, Chau FT, Dyke JM.
PMID: 15268255
J Chem Phys. 2004 Jan 15;120(3):1292-305. doi: 10.1063/1.1630559.

Potential energy functions (PEFs) of the X (1)A(') and A (1)A(") states of HSiF have been computed using the coupled-cluster single-double plus perturbative triple excitations and complete-active-space self-consistent-field multireference internally contracted configuration interaction methods, respectively, employing augmented correlation-consistent polarized-valence...

Visibility of comet nuclei.

Science. 1982 Jan 22;215(4531):397-8. doi: 10.1126/science.215.4531.397.

Photography of the nucleus of comet Halley is the goal of several planned space missions. The nucleus of a comet is surrounded by a cloud of dust particles. If this cloud is optically thick, it will prevent observation of...

The singlet-triplet separation in CF2: state-of-the-art ab initio calculations and Franck-Condon simulations including anharmonicity.

Chemphyschem. 2005 Oct 14;6(10):2037-45. doi: 10.1002/cphc.200500114.

Geometrical parameters, vibrational frequencies and relative electronic energies of the X2B1 state of CF2- and the X1A1 and ã3B1 states of CF2 have been calculated. Core-electron effects on the computed minimum-energy geometries and relative electronic energies have been investigated,...

A combined ab initio/Franck-Condon study of the A-X single-vibronic-level emission spectrum of CCl2 and the photodetachment spectrum of CCl2 -.
