Coherent X‐Ray Scattering for the Hydrogen Atom in the Hydrogen Molecule
The x‐ray form factors for a bonded hydrogen in the hydrogen molecule have been calculated for a spherical approximation to the bonded atom. These factors may be better suited for the least‐squaresExpand

Configuration interaction calculations on the nitrogen molecule
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. Second-order perturbation theoryExpand

One- and two-electron integrals over cartesian gaussian functions
A formalism is developed which allows overlap, kinetic energy, potential energy and electron repulsion integrals over cartesian Gaussian functions to be expressed in a very compact form involvingExpand

Distribution of effectively unpaired electrons
Abstract The density of effectively unpaired electrons employed recently by the authors [J. Am. Chem. Soc. 122 (2000) 186] is identical with the distribution D( r ) of `odd' electrons proposed muchExpand
