Abstract
The first high resolution infrared spectrum of the ionic complex $N_{2}-H^{+}-N_{2}$ and its deuterated derivative is reported. The spectra were obtained in direct absorption in a supersonic planar plasma. The observed rovibrational transitions were assigned to the antisymmetric NN stretching vibration and the spectrum is consistent with a linear centrosymmetric equilibrium structure. The band origin is found at $2352.2364(6) cm^{-1}$ and the ground state rotational constant is determined as $B^{\prime\prime} = 0.081809(14) cm^{-1}$. The assignment is supported by ab initio calculations. The best estimate for the equilibrium struture is $R_{e} (NN) = 1.095 {\AA}$ and $r_{e} (N-H)= 1.277 {\AA}$.$^{a}$
