Abstract
The excited states of $O_{2}$ in 100-135 nm region consists of many Rydberg states which are still not well understood. We have investigated the exited states of $O_{2}$ dissociated into $O(^{1}D)+O(^{3}P)$. The experiment was conducted in a gas cell using the synchrotron radiation as the excitation source. $O(^{1} D)$ was detected by the infrared emission at 762 nm produced from the $O_{2}(b^{1}\Sigma^{+}_{g})$ formed by the energy transfer process from $O(^{1}D)$ to $O_{2}$. A spectrum between 105 and 130 nm for producing $O(^{1} D)$ was obtained, which revealed the vibrational progression of the $n^{3}\Sigma^{-}_{u}$ states for n=2 to 4. By comparing with the absorption spectrum, the $^{3}\Pi_{u}$ state correlated with $O(^{3}P) + O(^{3} P)$ was also obtained.
