Abstract: 

High precision rotational spectra of isotopic oxygen O2 (with 16 O or 18 O) in its triplet Sigma electronic ground state have been measured in selected frequency regions between 0.4 and 2.0 THz. The main isotopic species, O2 , was also investigated in its first excited electronic state singlet Delta . The new data, analyzed together with previous measurements, yielded improved spectroscopic parameters.
