Understanding Electronic WaveFunctions
... experiments and theory are easier than is possible with extended solids since there are no finite size effects or pseudo-potentials to worry about. Let us try to generalize the Jastrow pair wavefunction of Eq.(5) to a molecule. The first problem is that the orbitals are not determined by translation ...

... Push-pull alkenes, consisting of one or two electron-donating groups (EDG) at the terminus of the C=C bond and one or two electron-withdrawing groups (EWG) at the other terminus, have been widely studied on the account of their low rotational barrier around the C-C double bond. This is attributed to ...
