Abstract:

Excited state systems of Mg0 have been examined by cw and pulsed dye laser fluorescence excitation spectroscopy. The B-a 0,0 and 0,1 and B-A 1,1, 2,2, and 2,1 bands have been analyzed deperturbed, and reduced to molecular constants. The deperturbation model quantitatively accounts for the oscillator strength in one nominally forbidden system through intensity borrowing from other systems. The most important use of the Mg0 B-a system will be proof, via OODR experiments now in progress, that the lambda 320nm continuum arises from Mg0 transition, thereby providing direct optical spectroscopic bounds to the dissociation energy of the Mg0 molecules. Four papers are in preparation describing the results of this research program.
