The effect of spin–orbit coupling on the ‘‘Newton’s cradle’’-type photodynamics in the cyclic disulfide 1,2-dithiane (C$ 4$H$ 8$S$ 2$) is investigated theoretically.We consider excitation by a 290 nm laser pulse and simulate the subsequent ultrafast nonadiabatic dynamics by propagating surface-hopping trajectories using SA(4|4)-CASSCF(6,4)-level electronic structure calculations with a modified ANO-R1 basis set…

Delayed photoisomerisation of the trans-PSB3 retinal toy model using on-the-fly quantum dynamics

We explore the trans–cis photoisomerisation process in a representative retinal protonated Schiff base known as trans-PSB3, employing the quantum dynamics method direct dynamics variational multiconfigurational Gaussian -DD-vMCG- in full dimensionality, i.e., 36 degrees of freedom on potential energy surfaces computed on-the-fly using the SA(2)-CAS(6,6)SCF electronic structure method with the 6-31G basis set…
