| Abstract: | The emission spectrum of ReN has been reinvestigated in the visible region using a Fourier transform spectrometer. Two new bands have been identified with band origins near 22 110 and 22 224 cm−1. These bands have a common lower state and have been assigned as the 0+–A1 and 0−–A1 transitions. After rotational analysis it was noted that the new 0+–A1 transition also has its upper state in common with the upper state of the [24.7]0+–X0+ transition reported previously [W.J. Balfour, J. Cao, C.X.W. Qian, S.J. Rixon, J. Mol. Spectrosc. 183 (1997) 113–118.]. This observation provides T00 = 2616.26 cm−1 for the A1 state. It is likely that the A1 and X0+ states are two spin components of the 3Σ− ground state. |
