The optical−optical double resonance time of flight (OODR-TOF) spectroscopy technique was employed to examine the 65 000−66 500 cm−1region of the nitric oxide spectrum. In this region, we detected the following three electronic states: E2Σ+(ν = 2) (Rydberg state), B2Π (ν = 23) (valence state), and L2Π (ν = 4) (valence state). The rotational structure analysis of an unexpected band in the red part of the spectra revealed the presence of a new super-excited2Σ+Rydberg state at ∼13.3 eV, which was populated through a three-photon transition from the intermediate A2Σ+(ν = 0) state. This super-excited state converges to the NO (a3Σ+) ionic state with electronic configuration (1σ)2(2σ)2(3σ)2(4σ)2(5σ)2(1π)3(2π)1(3sσ)1.
