Abstract
New recordings of the Nb II spectrum have been analyzed in the region 1500- 4900 Angstrom. 2025 lines have been classified, and all but three of the pr eviously known 67 even and 136 odd levels have been confirmed. New levels h ave been established, 117 even and 36 odd, giving a total of 353 known Nb I I levels.
