The spectra of water vapor enriched by O-18 were recorded in the 1000-2300 cm(-1) spectral range, which corresponds to the spectral region studied by IASI instrument (Infrared Atmospheric Sounding Spectrometer) instrument. The spectra were recorded by a step by step Fourier Transform Spectrometer (FTS) at room temperature with absorption path lengths up to 361111 Positions, intensities and self broadening coefficients of about 1800 lines of (H2O)-O-18 and 900 of (HDO)-O-18 were analyzed and all the transitions were assigned. This paper focuses on lines intensities and comparisons with data from literature are presented. An average difference of 10% with HITRAN2008 database (H2O)-O-18 line intensities is found with a maximum discrepancy of about 25% for the v(1)-v(2) band.
