Abstract:
The study of the absorption spectrum of the NO molecule has been continued on plates taken in the fourth order of a 10.5-m vacuum spectrograph. The spectra of 14 N 16 O, 15 N 16 O, 14 N 18 O, and 15 N 18 O gases, each kept at liquid-oxygen temperature, were photographed separately. Rotational analyses were carried out for many bands observed below 1 600 Å. Constants for levels of the Rydberg complexes 3p, 4s, 4p, and 5s have been derived. These levels include ν = 5 and ν = 6 of the C 2 Π state, levels that interact with the levels ν = 21 and 24 respectively of the configurationally different B 2 Π state. It is shown that the vibrational levels, now well established above the energy where the potential curves of the C and B states cross, are to be attributed to "crossing" curves.The level ν = 4 of the L 2 Π state, which was discerned in the spectra of the heavier isotopes only, coincides in 14 N 16 O with the level ν = 6 of C 2 Π and produces a strong three-level perturbation. The level, perturbed in this way, has the appearance of a separate electronic state in 14 N 16 O and at one time was so identified.Many interaction energies are determined, and the new systems of "deper-turbed" levels are thoroughly discussed.
