Experimental Transition Probabilities for Six Oxygen Multiplets

The transition probabilities of six oxygen-i multiplets in the visible and near infrared region have been measured in a wall-stabilized high-current arc operating either in pure oxygen or in a nitrogen-oxygen mixture. Temperatures were obtained from intensity measurements of an oxygen or nitrogen line of known transition probability and by applying the arc equilibrium and conservation equations. Several independent runs were carried out. The results agree usually within 20% with those of other experimental and theoretical methods.
