Program of the tutorials (PROPOSAL)
Tutorial n°1 (Monday p.m) : XMVB program
- Exercices from The Book ... >PCH< (30')
- Work with determinant (det) and with structures with H2
- use Atomic AO's, optimized VBSCF compare to HF CASSCF energies, looks at the coefficients.
- Pseudo states : compute |ab|+|ba| then only one determinant. Use it to for in situ bond energy evaluation [ethylene pi bond energy |ab| vs ground state( 4 determinants) ]
- FH (2 structures), F2 : VBSCF, different correlation wave functions (BOVB, VBCI,...), computation of weights and "charge-shift" character, also compare to CASSCF wave functions in the same basis set (probably to provide in order to avoid to spend time there).
Tutorial n°2 (Tuesday p.m): VB applications
- Exercices from The Book ... >PCH< (30')
- Benzen pi system dissymmetrization (2 geometries ; 2 computations on each )
- Benzen in GVB(6,6)
(trash: * O2 paradigm : compute singlet - triplet gap)
Tutorial n°3 (Wednesday p.m): VB vs BDO (Lewis structures) BLW & HuLiS
- Formamide VB & Lewis ; thioformamide, (Calcul et Comparaison Energie de resonance) Avec BLW DFT sur les fragmentations.
- Butadiene VB & Lewis
- Allyl radical and cation : MO, VB & Lewis ; ground state ? Excitation energy, gap ?? (SH : je laisse; c'est corrects?)
- Hyper conjugaison in ... ?
Tutorial n°4 (Friday p.m): State correlation diagrams
- VB & CASSCF ....
- Selected 1,3 dipoles (see with Philippe) : computation of 3-structure D-BOVB wave function, and of the biradical gap, correlation gap vs. barriers
- State correlation Diagrams : H3C. - H. - .CH3 (.... H bonds ???) other stuff.
