Excess Electrons Bound to H2S Trimer and Tetramer Clusters



Gaoxiang Liu, Manuel D?az-Tinoco, Sandra M. Ciborowski, Svetlana Lyspustina, Jay H. Hendricks, Vincent Ortiz, Kit H. Bowen


The hydrogen sulfide trimer and tetramer anions, (H2S)3– and (H2S)4–, were generated by Rydberg electron transfer and studied via a synergy between velocity-map imaging anion photoelectron spectroscopy and high-level quantum chemical calculations. The sharp peaks at low electron binding energy in their photoelectron spectra and their diffuse Dyson orbitals are evidence of them both being dipole-bound anions. While the dipole moments of the neutral (H2S)3 and (H2S)4 clusters are small, the excess electron induces structural distortions that enhance the charge-dipolar attraction and facilitate the binding of diffuse electrons.
