Excess Electrons Bound to H2S Trimer and Tetramer Clusters



Gaoxiang Liu, Manuel Díaz-Tinoco, Sandra M. Ciborowski, Chalynette Martinez-Martinez, 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.
