Spectroscopy of jet-cooled Bi3.
A resonant two-photon ionization spectroscopic study of jet-cooled Bi3 has identified two band systems in the molecule in the 9600-10 600 and 15 250-16 050 cm(-1) range. The latter of these has been previously observed in matrix isolation spectroscopy and tentatively attributed to Bi4; the mass-resolved work presented here reassigns it to Bi3. A review of all previously observed electronic states is presented, and it is argued that the new band system lying in the range 9600-10 600 cm(-1) corresponds to the spin-forbidden A' 4A1" <-- X1 2E" (E1/2 component) band system.
