Spectra of ozone generated from a 99.98% pure oxygen sample were recorded covering the $2800-3500cm-1$ at $0.010cm-1$ resolution with the McMath Fourier transform interferometer at the National Solar Observatory on Kitt Peak. The first extensive analysis of the 4 bands $3\nu 3,2\nu 3+\nu 1,2\nu 1+\nu 3$ and $3\nu 1$ absorbing in this spectral region has been performed leading to a precise set of rotational energy levels for the 4 vibrational interacting states ((003), (201), (102), (300)). These experimental levels were then reproduced with the aid of a Hamiltonian taking into account the various resonances (Coriolis, Darling-Dennison) affecting the levels. Moreover, using the equivalent width method, intensities of lines belonging to the four bands were measured with a relative uncertainty of about 10% and used to determine the corresponding transition moment constants. Finally, from the vibrational energies, rotational and coupling constants as well as transition moment constants a complete and precise list of the line positions and intensities of the $3\nu 3,2\nu 3+\nu 1,\nu 3+2\nu 1$ and $3\nu 1$ bands of $\mathrm{<mrow\; data-mjx-texclass="ORD">16</mrow>}O3$ has been generated.
