We report a photoelectron spectroscopic investigation of mono-nitrogen doped aluminum cluster anions AlnN- (n = 2-22). Well-resolved spectra were obtained at three photon energies (355, 266, and 193 nm), revealing the structural and electronic evolution as the number of aluminum atoms increases in the doped clusters. For small AlnN (n 12. This observation suggests that these clusters can be described as (AlN)Al-(n-1), i.e., an AlN unit weakly interacting with Al-(n-1) clusters. The electronic and atomic structural implications of this observation are discussed.
