The laser fluorescence excitation spectrum of the AlNe complex, in the vicinity of the Al atomic 3d←3p and 5s←3p atomic transitions, is reported. Transitions out of the v=0 vibrational levels of both lower-state spin-orbit levels, X1 2Π1/2 and X2 2Π3/2, to vibrational levels of the C 2Δ, D 2Π, and H 2Σ+ AlNe electronic states were observed. From observations of the onset of excitation to the Al(3d)+Ne dissociation continuum, dissociation energies for the various AlNe electronic states were determined. Ab initio calculations of AlNe electronic states correlating with the ground Al(3p)+Ne atomic asymptote were also carried out. The X1 2Π1/2 and X2 2Π3/2 binding energies computed using the calculated AlNe(X 2Π, A 2Σ+) potential energy curves were in reasonable agreement with the experimental determinations. The experimentally determined dissociation energy for the X2 2Π3/2 level is significantly larger than that of the ground X1 2Π1/2 level (D0=32.3±0.3 and 14.1±0.3 cm−1, respectively).
