Exploring conical intersection spaces using pseudo-dynamics and band optimization: a novel strategy Original Research Article

Recently, novel strategies based on pseudo-dynamics methods [T. Laino, D. Passerone, Chem. Phys. Lett. 389 (2004) 1] provided new technologies for sampling in an efficient way the seam of a conical intersection. In this contribution, after briefly reviewing the main features of our method, we show on one side how the results on ethylene anticipated in our previous paper are confirmed by calculation with a more accurate basis. Moreover, we show preliminary results on the topological properties of the seam of a retinal model fragment.
