Abstract
Submillimeter-wave rotational spectra of O$^{18}$O and $^{18}$O$_2$ in the $a^{1}\Delta_{g}$ state have been detected in a new static discharge cell useful for studying rare isotopologues of transient molecules. Rotational transition frequencies of both species have been measured through 1.6 THz, to better than 1 part in $10^{7}$, allowing precise determination of molecular constants. The first measurements with our static discharge cell provide a check on the isotopic predictions in the $a^{1}\Delta_{g}$ state.
