Vibrationally-resolved photoelectron spectra of AlMoO y - (y = 1-4) are presented and analyzed in conjunction with density functional theory computational results. The structures determined for the AlMoO y anion and neutral clusters suggest ionic bonding between Al + and a MoO y - or MoO y -2 moiety, and point to the relative stability of MoO versus AlO bonds. The highest occupied and partially occupied orbitals in the anions and neutrals can be described as Mo atomic-like orbitals, so while the Mo is in a higher oxidation state than Al, the most energetically accessible electrons are localized on the molybdenum center.
