Abstract
The long, irregular vibrational structure of the $\bar{B} (^{2}\Pi_{i})$ state of $N_{2}O^{+}$ is interpreted as a progression of Fermi resonances between pairs of vibrational subbands of the $\bar{B}$ state that correspond to $2\nu_{2} + (v-1)\nu 3$ and $v\nu_{3}$. Because of anharmonicity in the $\nu_{3}$ progression, the separations between successive pairs of interacting bands vary throughout the progression, resulting in variable magnitude Fermi interactions. This model, rather than the more usual one that incorporates overtones of $\nu_{2}$ is shown to accurately describe the experimental data.
