The spin dynamics within a chiral and achiral molecule was investigated. It was investigated through a diminishing periodic potential, depicting the molecules being dropped onto a substrate. Born-Oppenheimers approximation and a tight-binding model was used to describe the molecules. Moreover, Schrödingers equation was defined for the problem and an iterative approach was used to solve it. The results indicated an induced spin selectivity for the chiral molecule, which varied over time. In contrast, the achiral molecule exhibited weaker spin selectivity. This difference might lie in how the spin couples to the linear momentum in the different structures.
