Journal ArticleDOI
Femtosecond time-resolved photoelectron spectroscopy.
TL;DR: Femtosecond time-resolved or wave packet methods offer a view complementary to the usual spectroscopic approach and often yield a physically intuitive picture in discerning underlying dynamics.
Journal ArticleDOI
Observation of large water-cluster anions with surface-bound excess electrons.
Jan R. R. Verlet,Arthur E. Bragg,Aster Kammrath,Ori Cheshnovsky,Daniel M. Neumark,Daniel M. Neumark +5 more
TL;DR: In this article, the authors used photoelectron imaging to characterize a class of (H2O)n− and (D2On−)n-cluster anions with vertical binding energies that are significantly lower than those previously recorded.
Journal ArticleDOI
Hydrated Electron Dynamics: From Clusters to Bulk
Arthur E. Bragg,Jan R. R. Verlet,Aster Kammrath,Ori Cheshnovsky,Daniel M. Neumark,Daniel M. Neumark +5 more
TL;DR: The results support the “nonadiabatic relaxation” mechanism for the bulk hydrated electron mechanism and support the internal conversion lifetime of the p-state population decay with concomitant s-state repopulation.
Journal ArticleDOI
High Conductivity and Electron-Transfer Validation in an n-Type Fluoride-Anion-Doped Polymer for Thermoelectrics in Air.
Xingang Zhao,Deepa Madan,Deepa Madan,Yan Cheng,Jiawang Zhou,Hui Li,Susanna M. Thon,Arthur E. Bragg,Mallory E. DeCoster,Patrick E. Hopkins,Howard E. Katz +10 more
TL;DR: The result shows that using solution-processable small-anion salts such as TBAF as an n-dopant of organic conjugated polymers possessing lower LUMO (lowest unoccupied molecular orbital), less than -4.2 eV) can open new opportunities toward high-performance air-stable solution- Processable n-type thermoelectric (TE) conjugate polymers.
Journal ArticleDOI
Aminofluorination of Cyclopropanes: A Multifold Approach through a Common, Catalytically Generated Intermediate
TL;DR: Calculations suggest that solvent may play an important role in the cyclopropane ring-opening step, and transient-absorption experiments have allowed direct spectroscopic observation of radical ion intermediates and have provided kinetic support for chain propagation.
