ResumoThe two-photon ionization spectra of the Li3 molecule have been systematically investigated. A new spectroscopic system corresponding to the C state has been observed. The hot bands of the A←X and C←X transitions have been recorded at various temperatures. The assignment of these bands allows us to determine completely the ground-state potential surface. The results obtained lead to a quasi-free pseudo-rotation motion even in the lowest vibronic level.
