Optical and Dynamical Properties of Metal Clusters

The spectroscopy of Na3 has been systematically investigated with different techniques: Two-Photon Ionization (TPI) and Depletion Spectroscopy (DS). Four excited electronic states have been found in the range from 850 nm to 330 nm. The lifetime measurement of these states suggests that the highly excited ones are partially or totally predissociated. For this reason depletion spectroscopy has been used, and reveals the complete structure of the predissociated C-state. The Na3 ground state has been investigated by hot band analysis. This allows a precise comparison with the calculations.
