Hello! Is there any diatomic molecule containing Al (or even a molecular ion), which upon dissociation from a given electronic level, leaves behind Al as a neutral atom? Any reference is appreciated. Thank you!
Yes, the aluminum monoxide (AlO) molecule is a diatomic species that can dissociate from its electronic ground state into a neutral aluminum atom and an oxygen radical. This dissociation is also known as AlO photodetachment. References: 1. Kolesar, J., and E. W. Draeger. "Photodetachment of Aluminum Monoxide: A Theoretical Study."
