The spectrum of rhenium was observed in the (1017–2074) Å wavelength region. The (5d{sup 5} + 5d{sup 4}6s)–(5d{sup 4}6p + 5d{sup 3}6s6p) transition array of two times ionized rhenium, Re III, has been investigated and 1305 spectral lines have been classified in the region. The analysis has led to the determination of the 5d{sup 5}, 5d{sup 4}6s, 5d{sup 4}6p and 5d{sup 3}6s6p configurations. Seventy levels of the 5d{sup 5} and 5d{sup 4}6s configurations in the even system and 161 levels of the 5d{sup 4}6p and 5d{sup 3}6s6p configurations in the odd system have been established. The orthogonal operators technique was used to calculate the level structure and transition probabilities. The energy parameters have been determined by the least squares fit to the observed levels. Calculated transition probability and energy values, as well as LS-compositions obtained from the fitted parameters are presented.
