On the Role of the Electron-Dipole Interaction in Photodetachment Angular Distributions

The importance of including long-range electron-molecule interactions in treatments of photodetachment/photoionization is demonstrated. A combined experimental and computational study of CN− detachment is presented in which near threshold anisotropy parameters (β) are measured via photoelectron imaging. Calculated β values, based on an EOM-IP-CCSD/aug-cc-pVTZ Dyson orbital, are obtained using free particle and point dipole models. The results demonstrate the influence of the molecular dipole moment in the detachment process, and provide an explanation of the near threshold behavior of the overall photodetachment cross section in CN− detachment [J. Chem. Phys. 2020, 153, 184309]

Ultrafast decay dynamics of electronically excited 2-ethylpyrrole

A combined photoelectron-imaging spectroscopic and theoretical investigation on the electronic structure of the VO2H anion

The PES of VO2H− was detected at 814 nm. The electronic configuration of anionic and neutral of VO2H is 4A′′ and 3A′′, respectively. The electron was detached from the s-type 17a′ MO of the anionic ground state of VO2H.
