In this part, we describe the way to record and analyze ozone spectra. The
first section ("FTS") is devoted to the description of the FTS working in stepping
mode; the second one ("Facilities") describes the facilities (sources, cells, ...) and the
next the experimental set up as ozone generation or pressure measurements.
The way to calculate synthetic spectra is given in "Synthetic spectra" section.
Data reduction in described in next section
allows to derive experimental parameters as positions, intensities, or pressure
shift and broadening. The spectra, covering all spectral range from 750 to
6000 cm-1, associated with there experimental recording
conditions. These spectra allow to check S/N ratio and resolution. The following
paragraph (Assignment) explains the assignments of lines: impurities and ozone. The last
presentation shows various examples of agreement between observed and
