Date & Time: Sep 22 2025 | 11:30am - 12:30pm Location: iSTEM Building 2, Room 1218 Azulene, a 10-π-electron aromatic molecule, is widely used as a test system due to its bright S₂ singlet state, exhibiting anti-Kasha behavior. Despite extensive studies, its gas-phase time dynamics remain controversial. We revisited Azulene in a jet-cooled molecular beam to address these dynamics with a newly developed Ultrafast Resonance-Enhanced Multiphoton Ionization (REMPI) system. In addition, we obtained the first gas-phase REMPI spectrum of the Azulene dimer. This dataset will serve as a benchmark for developing the next-generation Cavity-Enhanced Transient Absorption Spectrometer with optical frequency tunability.
