    • Abstract


      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 toAX,BX,CX andDX transitions. Vibrational analysis was carried out for each of the systems mentioned above.A2 Δ has been suggested as the ground state of NiBr molecule with an electronic interval of about 533 cm−1. Transitions responsible for NiBr spectrum appear to be of the type2π–2Δ and2Δ–2Δ.
