Tellurium spectra were recorded on a 3 m normal incidence vacuum spectrograph in the spectroscopy laboratory of St. Francis Xavier University using a triggered spark light source. The spectrum of the singly ionized tellurium atom was investigated in the wavelength region 746-1838 Å using Hartree-Fock configuration interaction calculations involving 5s 2 5p 3 , 5s5p 4 , 5s 2 5p 2 (5d + 6d + 7d + 8d + 6s + 7s + 8s + 9s) configurations. Earlier analysis by Handrup and Mack has been revised, and 27 new energy levels have been added, to complete the 5s 2 5p 3 , 5s 2 5p 2 (5d + 6d + 6s + 7s) configurations. Now five levels of the ground-state configuration and 78 of the excited configurations are known. Two hundred and nineteen spectral lines have been classified in this spectrum. Least squares fitted parametric calculations were used for the final interpretation and LS percentage compositions. The wavelength accuracy of our measurement for unblended and sharp lines is ±0.005 Å.
