Abstract
The orange bands of FeO are excited in a low pressure arc in oxygen and photographed at dispersions of 0·8 and 0·5 Å/mm. respectively. Rotational analysis of five of the bands shows that they involve a1 Σ-1 Σ transition. The vibrational and rotational constants (in cm.−1) of the upper and lowerΣ states are found to be
In the low-pressure arc it is found that highly excited atomic lines appear very much reduced in intensity in contrast to spectra excited in an arc at atmospheric pressure.
