    Notes: The metastable O(1D) atom produced in the photodissociation of O2 in the wavelength region 113–130 nm was detected by measuring the 762 nm fluorescence of the transition O2(b 1Σg+→X 3Σg−). The excited states of O2 were classified as either the 3Σu− state that produces O(1D)+O(3P), or the 3Πu state that produces O(3P)+O(3P). Our quantum yield measurements of O(1D) found bands of both pure and overlapped 3Σu− and 3Πu states. Five bands were found to produce O(1D), including the longest, second, and third bands and two additional bands near 115.3 and 113.8 nm that were assigned as the E 3Σu−(v′=3–4) states. Three bands were assigned to the F 3Πu(v′=0–2) state. We also found a state at 116.2 nm, which did not produce O(1D), but produced weak visible fluorescence. The possibility of attributing the fluorescence to a transition D 3Σu+–C 3Πg was discussed. © 2000 American Institute of Physics.

    Detection of O(1D) produced in the photodissociation of O2. II. Identification of the 3Σu− and 3Πu Rydberg states in 105–113 nm (2001)

    Notes: The production of O(1D) from O2 by photodissociation was measured in the 105–113 nm wavelength region. The quantum yields of O(1D) were employed to identify the excited states as 3Σu− or 3Πu, where the former correlated with the production of O(1D) and the latter production of O(3P) only. Many bands of E, E′ of 3Σu− and F, F′ 3Πu, were found with their vibrational states identified. Several bands had mixed states, such as the (0,0) and (1,0) bands of D′ 3Σu−←X 3Σg− transition which had smaller than unity quantum yields of O(1D) due to the perturbation caused by the nearby states D′ 3Σu+(v′=1,2) at 112.0 and 110.0 nm. The bands of npσu 3Πu state in the region of 105–110 nm are in agreement with the assignments of other works, and a band near 107.3 nm is consistent with the predicted band position of the F 3Πu(v′=6) upper-state. © 2001 American Institute of Physics.
