return to Tutorial n°4 Two geometries are provided the planar and the twisted where a vinyl part C1 C5 has been twisted by 90°. this second moieties has its pi orbitals along the y direction.

planar.inp and planar-deconj.inp

Localization of px-like pi orbitals to deconjugate keeping planar

twisted.inp and twisted-blw.inp

In the BLW part we localize px-like pi orbitals of atoms C2 and C6 and py-like orbitals for C1 C5 to avoid hyperconjugaison.
