Journal ArticleDOI
Coherent X‐Ray Scattering for the Hydrogen Atom in the Hydrogen Molecule
TL;DR: In this paper, the x-ray form factors for a bonded hydrogen in the hydrogen molecule have been calculated for a spherical approximation to the bonded atom, and the corresponding complex scattering factors have also been calculated.
Journal ArticleDOI
Configuration interaction calculations on the nitrogen molecule
TL;DR: In this article, a contracted Gaussian basis set capable of describing about 63% of the correlation energy of N2 has been used in a detailed configuration-interaction calculation, and second-order perturbation theory overestimated the correlated energy by 23-50% depending on how H0 was chosen.
Journal ArticleDOI
The iterative calculation of a few of the lowest eigenvalues and corresponding eigenvectors of large real-symmetric matrices
Journal ArticleDOI
Ligand spin polarization and antiferromagnetic coupling in transition metal dimers
TL;DR: In this paper, it was shown that spin polarized determinants for an antiferromagnetic transition metal dimer and spin projected states obtained from them contribute to the Heisenberg coupling constant J describing a ladder of spin states.
Journal ArticleDOI
Basis Set Selection for Molecular Calculations
Ernest R. Davidson,David Feller +1 more
TL;DR: In this article, the authors consider the problem of finding a set of functions which is flexible enough to produce 'good' results over a wide range of molecular geometries and is still small enough to leave the problem computationally tractible and economically within reason.
