For the time-evolution we will use the TDH method to propagate the dynamics. The TDH state is initialized from a VSCF state obtained on an initial PES supplied beforehand and the dynamics are then propagated in time on a different PES. In order to test the accuracy of the simulation when using the TD-ADGA method to obtain the potential during the simulation, we will also carry out an identical TDH simulation but where the potential of the second curve has been supplied beforehand by a TI-ADGA calculation. We will use the Extended Rydberg fits to calculate SPs in both the TI-ADGA and TD-ADGA calculations and the PESs that we use in the TDH simulations will be all fitted using 12th order polynomial fits.
