Probing the Quantum Nature of Intramolecular Vibrational Energy Redistribution in HCCH-H2CC Isomerization Using High-Resolution Photoelectron Spectroscopy.
High resolution photoelectron spectra of vinylidene anions (H2CC- and D2CC-) are reported using variations on slow electron velocity-map imaging of cryogenically cooled anions (cryo-SEVI). This work builds on previous studies aimed at exploring the coupling between neutral H2CC and HCCH isomers. One-photon photodetachm...
