The Spectrum of RuC in the Region 6 000-8 700 Å

Abstract

The emission spectrum of RuC obtained in a King furnace has been photographed in a high resolution Eagle spectrograph between 6 000-8 700 Å. 46 bands were detected in this region. From a vibrational analysis it seems most likely that they belong to 8 sub-systems. The final arrangement of these sub-systems into systems has not been successful. For the most intense sub-system with the 0-0 band situated at 7 224 Å the following molecular constants in cm-1 were derived:
