Abstract: The $(11^{1} 0) \leftarrow (01^{1} 0)$ hot band of protonated nitrogen ($N_{2}H^{+}$) has been measured using a color center laser and the technique of velocity modulation. High-J (up to J=40) lines, in addition to those previously reported (1), have also been measured in the $\nu_{1}$ vibration. This data was combined with the relevant published work to enable an equilibrium structure to be calculated. Rotational transitions have been reported by Szanto et al. (2), Van den Heuval and Dymanus (3) and Sastry et al. (4). The $\nu_{2}$ bands of $N_{2}H^{+}$ and $N_{2}D^{+}$ have been observed by Sears. (5,6). The $\nu_{j}$ of $N_{2}H^{+}$ and $N_{2}D^{+}$ have been measured by Foster and McKellar (7) while the $\nu_{1}$ and $(11^{1} 0) + (01^{1} 0)$ hot band have been observed by Nesbitt et al. (8). These data have been combined in a weighted least squares analysis to yield rotational constants, centrifugal distortion constants and 1-type doubling constants. Using this information, we have calculated the equilbrium structure of protonated nitrogen.
