| Abstract: | Resonance Raman spectra of bismuth molecules reveal two progressions with ωe = 172 and 152 cm?1 The metal concentration dependence allows us to assign the 172 cm?1 band to Bi2 and the 152 cm?1 band to a larger molecule, most likely Bi4. Thus the existence of an X' ground state of Bi2 ≈ 1500 cm?1 below the X state can be excluded. |
