A Rydberg wave packet is a superposition of multiple, highly excited electronic states (Rydberg states). The evolution of these wave packets exhibits radially oscillating charge density with fixed revival times [1]. These radial charge density oscillations could prove chiral sensitive in a chiral molecular potential. This Project aims to probe the Rydberg wave packet dynamics in the chiral molecules fenchone and thiofenchone using time-dependent photoelectron circular dichroism (PECD). PECD is defined as the forward-backward asymmetry in photoelectron distribution with respect to the laser propagation direction in chiral molecules ionized with circularly polarized light [2]. In this contribution, we will provide preliminary data and report on the project's current status. [1] Fielding, H. H., Ann. Rev. Phys. Chem., 56, 91-117 (2005) [2] Lux, C. et al., Angew. Chem. Int.
