The photoelectron spectra of NO have been remeasured with 584 Å and 304 Å He lines at high resolution and the energies of the bands have been determined by calibration against argon. A weak He I line 320.4 Å has been found to cause the small peak at 20.4 eV, which was assigned earlier as the c 3II state. The c 3II and B 1II states have nearly the same energy, 21.7 eV. The vibrational structure of the B′ 1Σ+ state at 22.5 eV has been resolved.

A Journal of Physical Sciences: Zeitschrift für Naturforschung A (ZNA) is an international scientific journal which publishes original research papers from all areas of experimental and theoretical physics. In accordance with the name of the journal, which means “Journal for Natural Sciences”, manuscripts submitted to ZNA should have a tangible connection to actual physical phenomena.
