Using $0.005-cm-1$ resolution room temperature Fourier transform spectra of $\mathrm{<mrow\; data-mjx-texclass="ORD">17</mrow>}$O-enriched ozone samples, the first extensive analysis of the $\nu 2$ bands of $\mathrm{<mrow\; data-mjx-texclass="ORD">15</mrow>}O17O16O$ and $\mathrm{<mrow\; data-mjx-texclass="ORD">15</mrow>}O16O17O$ has been performed. First, using ground state combination differences derived from the infrared spectra together with the available microwave transitions, the ground state constants were refined. Then, the (010) rotational levels were fitted leading to precise constants for the upper states of both molecules. Finally, using appropriate expansions of the transformed transition moment operators, it has been possible to generate a comprehensive list of the line positions and intensities for the $\nu 2$ bands of both isotopic species.
