Abstract

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^-.
