摘要
Very low energy electron attachment to DMSO and DMSO-water clusters is studied by means of the Rydberg electron-transfer spectroscopy method. Only DMSO- and (DMSO-H2O)(-) anions, with excess electrons in diffuse orbitals, are observed, and the corresponding excess electron-binding energies are, respectively, 12.7 and 3.6 meV. The relative energies and equilibrium geometries of DMSO, DMSO-H2O, and their anions are determined by means of MP2 and DFT calculations and compared to experimental results.
