Abstract

Two sequences of the quartet system of NO1 at 7900 {\AA} (Δν=4) and at 8700 {\AA} (Δν=3) have been rephotographed at high resolution. The spectra were obtained from a dc discharge in a supersonically expanding jet2 of He + NO. The low rotational temperature achieved in the jet (∼50K) results in a striking simplification of the previously very congested band structures, making it possible to proceed with a detailed rotational analysis.
