N2 - Mg+-Ar ion-molecule complexes are produced in a pulsed supersonic nozzle cluster source. The complexes are mass selected and studied with laser photodissociation spectroscopy in a reflectron time-of-flight mass spectrometer system. An electronic transition assigned as X 2Σ+ → 2Π is observed with an origin at 31387 cm-1 (vac) for 24Mg+-Ar. The 24Mg+-Ar spectrum is characterized by a 15 member progression with a frequency (ω′e) of 272 cm-1. An extrapolation of this progression fixes the excited state dissociation energy (D′o) at 5552 cm-1. The corresponding ground-state value (D″o) is 1270 cm-1 (3.6 kcal/mol). The 2Π 1 2, 3 2 spin-orbit splitting is 76 cm-.
