... double bond in ethene (CH2=CH2)? Answer: Two carbon p atomic orbitals overlap side-to-side and in phase to form the p bond that is present. Rotation about the carbon-carbon bond axis requires quite a bit of energy because the p bond is broken as the overlap between the two p orbitals is disrupted. D ...

Comparison of density functionals for energy and structural
... An important goal of this paper is the comparison of the relative ability of density functionals to treat different spin states. This may be termed the ‘‘DFT pairing-energy problem.’’ Although this name is particulary appropriate when considering applications to transition metal coordination complex ...
