During a new investigation of the NO band spectrum many bands of the β and γ system were photographed and analysed, and the rotational constants evaluated. Intensity drops and perturbations were found and two predissociation limits at 53800 and 50500 cm-1 were established. In this way the dissociation energy of NO is fixed at 4.29 eV. The X2π ground state of NO dissociates in the N(2D)+O(3P) atomic term combination. The new dissociation scheme is strongly supported by the results of photochemical experiments.
