Two electronic transitions are observed for a new heteronuclear dimer, AlNa, using two-color two-photon ionization spectrocopy (2R2PI). The combination of the analysis of vibronic structure and ab initio calculation enables us to assign the two transitions as D 1Π←X 1Σ+ and C 1Σ+←X 1Σ+; the origins of the D and C states are located at 16427 and 15422 cm-1, and the vibrational frequencies being 151 cm-1 in the D state, 115 cm-1 in the C state, and 186 cm-1 in the X state, respectively.
