The excited states of O2 in 100-135 nm region consists of many Rydberg states which are still not well understood. We have investigated the excited states of O2 dissociated into O(1D)+O(3P). The experiment was conducted in a gas celll using the synchrotron radiation as the excitation source. O(1D) was detected by the infrared emission at 762 nm produced from the O2(b1g+) formed by the energy transfer process from O(1D) to O2. A spectrum between 105 and 130 nm for producing O(1D) was obtained, which revealed the vibrational progression of the n3u- states for n=2 to 4. By comparing with the absorption spectrum, the 3u state correlated with O(3P)+O(3P) was also obtained.
