However, the current ability to probe chirality on the time scale of primary processes underlying chemical reactions remains very limited. Here, we demonstrate time-resolved photoelectron circular dichroism (TRPECD) with ultrashort circularly polarized vacuum-ultraviolet (VUV) pulses from a tabletop source. We demonstrate the capabilities of VUV-TRPECD by resolving the chirality changes in time during the photodissociation of atomic iodine from two chiral molecules. We identify several general key features of TRPECD, which include the ability to probe dynamical chirality along the complete photochemical reaction path, the sensitivity to the local chirality of the evolving scattering potential, and the influence of electron scattering off dissociating photofragments. Our results are interpreted by comparison with high-level ab-initio calculations of transient PECDs from molecular photoionization calculations. Our experimental and theoretical techniques define a general approach to femtochirality."}],"issue":"28","publication_status":"published","extern":"1","date_published":"2022-07-15T00:00:00Z","date_updated":"2023-08-22T07:24:01Z","pmid":1,"article_processing_charge":"No","month":"07","day":"15","type":"journal_article","keyword":["Multidisciplinary"],"year":"2022","volume":8,"intvolume":"         8","language":[{"iso":"eng"}],"_id":"13992","article_number":"abq2811","article_type":"original","citation":{"ieee":"V.
