Abstract
For Bi2 molecules in argon matrices, a new laser‐induced fluorescence system with origin at 16 893 cm−1 has been observed. The upper state A′ lies 826 cm−1 below the well‐established A state. A progression of six bands of the resonance Raman spectrum of Bi2 is also reported. More concentrated matrices display an extremely weak fluorescence which is very probably the B–X system of Bi4, previously observed in absorption. A sequence of resonance Raman bands with an irregular intensity pattern is attributed to an unknown Bin molecule.Keywords
