The A-X transition of diatomic bismuth, Bi2, was revisited by laser induced fluorescence in solid Ne at 3 K. Molecular constants, i.e., vibrational frequencies of 137 cm-1 and 174 cm-1, were reproduced for the upper and lower electronic states as reported by Bondybey et al. [Chem. Phys. Lett. 76, 30 (1980)]. Two-dimensional mapping of emission spectra confirmed satellite bands in higher and lower excitation/emission energies for each of the major bands in the vibrational progression of v′-v″ (v′ = 0.5, v″ = 5-12). Based on the molecular orbital cal-culations, presence of clusters, Bi2Nen (n = 1-6), is proposed for possible carriers of the observed satellites. For the relatively large matrix shift of ∼ 67 cm-1 in solid Ne for the term energy of the A state, the diatomic bismuthis supposed to exist as a linearly coordinated cluster of Bi2Ne in the matrix.
