The photochemical ring opening process in pyrrole has been investigated by means of on-the-fly dynamics using the MSCSC method for the computation of energies and energy gradients. As starting point for the dynamics the conical intersection corresponding to the ring-puckered ring-opened structure has been chosen. Within the simulation time of 1 ps, ring opening of pyrrole to the biradical NH=CH–CH•–CH=CH• chain followed by ring closure to a substituted cyclopropene structure (NH=CH–C3H3) is observed. The computed structural data correlate well with the experimentally observed dissociation products.
