The ultraviolet (1, 0) B ^{2}Σ_{u}^{+} - X ^{2}Σ_{g}^{+} transition in the N_{2}^{+} cation was measured with the absorption cavity ring down technique. The N_{2}^{+} cations were produced in a stationary DC discharge in nitrogen under reduced ( ≈ 0.5 Tr) pressure. The weak band due to the (4, 0) A ^{2}Π_{u} - X ^{2}Σ_{g}^{+} transition in the red part of the spectrum was also recorded. Several of the observed transitions correspond to absorptions from the vibrationally excited (ν'=1) states of N_{2}^{+} and to absorptions from the neutral N_{2} molecules in the triplet state.
