Abstract

In order to aid in the interstellar identification of molecular oxygen via its ¹⁶O¹⁸O isotopic species, we have measured the frequencies of four rotational fine-structure lines of ¹⁶O¹⁸O at frequencies ranging from 298 to 464 GHz. The line with the highest intensity and consequent best chance of astronomical detection lies at 401739.823 MHz. Its magnetic dipole strength is somewhat more than half that of the previously measured strong line at 233946.179 MHz.
