Fluorescence Studies of Laser Vaporized Aluminum: Evidence for a 3πu Ground State of Aluminum Dimer.

Abstract

Aluminum is an element of considerable importance in chemistry and technology. Simple aluminum containing molecules, including Al2 dimer were therefore extensively studied, both experimentally1-3 and theoretically.4-8 While some theoretical studies and a previous gas phase study suggested a ground state of 3∑g symmetry, and some matrix studies claimed a 1∑ ground state, other theoretical works predicted an X 3πu ground state.
