β¦ Synopsis
The electronic structures of bi.rsdica!s are investigated by the unrestricted h'~trec-Fock (UHF) method and explained in terms of spin density wave (SDW) orbitals. The blrodiclii characters arc calculated by the USC of the occupation numbers of ?hl: natural orbit& in the SDW configuration. The results are wholly compstible with those of other methods of calculation.

## Abatnct-An important question in elcctrosorption bond theory is how does the partial charge transfer coefficient dcpcnd on the electrode potential. In this paper, we report a systematic study of this question using a model which is simple enough so that hydrogen clectrosorption can be treated i
Curve crossing in a simple two-electron two-orbital model is considered. It is shown that the spin density wave (SDIi? solution has the correct crossing points and is closest to the exact solution of ali single determinants.
