Abstract
The metal ion-complex $^{24}Mg^{+}Ar$ has been prepared in a pulsed nozzle/laser vaporization sources and studied with mass selected photodissociation spectroscopy at high resolution using a reflectron time-of-flight mass spectrometer. The (5,0) band of the $A{^{2}}\Pi,-X^{2}\Sigma^{+}$ transition has been rotionally analyzed and the constants $T_{50}=32753.384(17) cm^{-1}, A' = 73.94(2) cm^{-1}, B""=.1409(7) cm^{-1}$ and $B^{\prime} = .1836(8) cm^{-1}$ have been determined. The bond distances in the ground and excited states of the complex $({r_{0}}^{\prime\prime}=2.88 \AA, {r_{5}}^{\prime}=2.52 \AA)$ compare well with the theoretical values. Further results on the complex $Mg^{+}Kr$ will be presented as well.
