Tutorial n°2 (Tuesday p.m): VB applications (A. Shurki + D. Danovitch)

Sason remarks and prospective 2 hours talk +

Philippe's remark on the initially proposed tutorial. are included in bold.

Qualitative

• Exercices from The Book ... >PCH< (30')

Computational

• Allyl cation : VB 3 configuration (3rd configuration has a large weight).
• Benzyl radical with most spin alternant determinants (2 determinants) (p228 of The Book) show spin location. Objection : this uses Heisenberg spin hamiltonian theory, a topic that we do not teach.

* H2O lone pairs : compute H2O+ states (2 configurations mixing)

• R-X bond dissociation to R. .X and R(+) (-)X for stable ionic dissociation ... via solvent effects? (is that possible with xiamen ?)

(trash: * O2 paradigm : compute singlet - triplet gap : too hard)
