Abstract :
The photoelectron spectra of Au−(H2O)1,2, Au 2 - (D2O)1–4, and AuOH− have been measured. The anionic complexes, Au−(H2O)1,2 and Au 2 - (D2O)1–4, were characterized as Au− and Au 2 - , which are respectively solvated by water molecules. The stepwise spectral shifts between adjacent size species have been quantified. The photoelectron spectrum of AuOH− exhibits considerable vibrational structure. Based on our assignment of its spectrum, the adiabatic electron affinity of AuOH was determined to be 1.771 ± 0.015 eV.
