MgD 2 + ion-molecule complexes, produced in a liquid-nitrogen-cooled laser vaporization source, are massselected and studied by laser photofragmentation spectroscopy in a reflection time-of-flight mass spectrometer. We have observed molecular absorption to the red of the Mg + (3 2 S 1/2 -3 2 P J ) atomic resonance lines. Notably, the reactive daughter ion (MgD + ) is the only fragmentation product clearly observed in this spectral region. The molecular absorption profile consists of a seven-membered progression of discrete vibrational transitions with decreasing vibrational spacings from 489 to 314 cm -1 , superimposed on a broad continuum background
