The extensive thermal emission spectrum attributed to the diatomic bromides of calcium, strontium and barium has been observed in the visible region at temperatures about 2200–2400° C, using a vacuum graphite furnace. Many new bands,
Volume 15 Issue 4 October 1980 pp 349-356 Molecular Physics
Thermal emission spectrum of NiBr molecule excited by vacuum graphite tube furnace revealed the existence of ten new band sub-systems in the region λλ 5540-4720 Å which were attributed to

Thermal emission spectrum of YbI molecule has been photographed for the first time in the spectral region
Volume 43 Issue 1 July 1994 pp 73-80
Thermal emission spectrum of MnSe molecule, excited in high temperature graphite furnace, has been photographed in the spectral region λλ4150–5800 Å at a reciprocal linear dispersion of 7.3 Å/mm. The study reveals the presence of two band systems viz.
An estimation of the ground state vibrational frequency for MnTe molecule gives rise to its value as 280 cm−1.
