Abstract:

Size-selective cryogenic photoelectron spectroscopy (cryoPES) coupled with electrospray ionization source (ESI) has been demonstrated to be a powerful experimental technique to investigate electronic structures and energetics of a wide variety of solution phase species and chemistry in the gas phase. In this talk, I will present the latest results probing various novel molecular clusters ranged from closo-dodecaborate dianions [B₁₂X₁₂]^2- to atmospherically relevant species by employing this technique. Transition state dynamics of unimolecular isomerization and chemical reactions via photodetachment of corresponding precursor anions will be reported as well. Future directions of ESI-cryoPES, leading to high resolution photoelectron imaging spectroscopy and time-resolved pump-probe experiments will also be briefly discussed.
