The metal ion-complex $\mathrm{<mrow\; data-mjx-texclass="ORD">24</mrow>}Mg+Ar$ 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 $A\mathrm{<mrow\; data-mjx-texclass="ORD">2</mrow>}\Pi ,-X2\Sigma +$ transition has been rotionally analyzed and the constants $T50=32753.384(17)cm-1,A\prime =73.94(2)cm-1,B""=.1409(7)cm-1$ and $B\prime =.1836(8)cm-1$ have been determined. The bond distances in the ground and excited states of the complex $(r0\prime \prime =2.88\backslash AA,r5\prime =2.52\backslash AA)$ compare well with the theoretical values. Further results on the complex $Mg+Kr$ will be presented as well.
