Measurements of the electronic transition moments of C 2-band systems

Abstract

Electronic transition moments of seven C 2 singlet and triplet band systems, which are in the 0·2−1·2μm spectral region, have been measured. The measurements were made in emission behind incident shock waves in C 2H 2-argon mixtures. Narrow band-pass radiometers were used to obtain absolute measurements of shock-excited C 2 radiation from which absolute electronic transition moments are derived by a synthetic spectrum analysis. New results are reported for the Ballik-Ramsay, Phillips, Swan, Deslandres-d'Azambuja, Fox-Herzberg, Mulliken, and Freymark Systems.
