Abstract

Zero kinetic energy (ZEKE) photoelectron spectroscopy has been employed to study the spectroscopy and the geometry of the sodium cluster Na₃⁺ with nanosecond tunable dye lasers. The fully resolved cation vibrational spectra prove the equilateral (D_3h) geometry of Na₃⁺. Due to the high resolution of the ZEKE method we derived a much improved value for the ionization potential of Na₃ of 31,363 +/- 5 cm^-1, which is about 300 cm^-1 lower than previous values. The real- time dynamics of two photon ionization and fragmentation of Na₃ has been studied applying femtosecond pump-probe techniques in combination with ion- and ZEKE photoelectron spectroscopy. Three dimensional vibrational wave packet motions in the excited state B and in the ground state X as well as pseudorotational wave packet motion in the B-state have been observed. Time resolved fragmentation studies show ultrafast picosecond decays of most of the excited states of Na₃.
