Journal ArticleDOI
Perturbation theory for open shell systems
TL;DR: In this paper, two new forms of perturbation theory are presented that are applicable to open shell systems, based entirely on the restricted open shell Hartree-Fock formalism and can be used on the lowest energy of a given symmetry at that geometry.
Journal ArticleDOI
Theoretical studies of diradicals containing four .pi. electrons
Journal ArticleDOI
Diradical Character of the Cope Rearrangement Transition State
Journal ArticleDOI
Improved Algorithms for the Lowest Few Eigenvalues and Associated Eigenvectors of Large Matrices
TL;DR: In this paper, a method for solving the equations stemming from the quasi degenerate variational perturbation theory is presented, which can be obtained as simply as with the eigenvalue algorithm for both ground and excited states.
Journal ArticleDOI
A possible definition of basis set superposition error
TL;DR: In this article, a new definition is suggested for basis set superposition error and other sources of basis set incompleteness error in the interaction energy are considered Comparison is made with the counterpoise correction.
