Rotational structure of the absorption coefficient in the range 1220 A~-1223 A arising from the 3-0 band of the ~ 1Z/-X3Z~ forbidden transition in molecular oxygen is clearly resolved in the present measurements. A transition probability of A=4 • 104 s -1 is obtained for this system. A careful study of a possible pressure dependence of the absorption coefficient was made. Except from the region were rotational line absorption occurs and the single point at 1 215.70 A no measurable effect was found for pressures below 100 Torr.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
