Abstract
The emission spectrum of NbN has been reinvestigated in the 8000-35000 cm(-1) region using a Fourier transform spectrometer and two groups of new bands were observed. The bands observed in the 18 000-20 000 cm(-1) region have been assigned to a new (3)Pi-X-3 Delta transition. Three bands with R heads near 19463.8, 19659.0 and 19757.0cm(-1) have been assigned as 0-0 bands of the (3)Pi(2)-X-3 Delta (3)Pi(1)-X-3 Delta(2) and (3)Pi(0 +/-)-X-3 Delta(1), subbands, respectively, of this new transition. Three additional Delta Omega = 0 bands have been observed in the 24 000-26 000 cm(-1) region. A 0-0 band with an R head near 25 409.9 cm(-1) has been assigned as a Delta Omega = 0 transition having X-3 Delta(2) as its lower state while two additional bands with heads near 25518.7 and 25534.8 cm(-1) were found to be Delta Omega = 0 bands having X-3 Delta(1) as the common lower state. Two of these three bands are perhaps subbands of a (3)Delta-X-3 Delta transition. Most of the excited levels are afrected by perturbations. (c) 2007 Elsevier Inc. All rights reserved.
