Numerous lines were observed in the UV absorption spectra of O 2 doped in a low-temperature Ar crystal excited by a KrF excimer laser. These lines were assigned to the transitions from vibrationally excited levels of the ground state O (v" = 4-11) to vibrational levels of the B state (v' = 0-8), whe
