Abstract: The purpose of this work was to obtain reliable absolute intensities for the $\nu_{6}$ band of $H_{2}O_{2}$. This work was undertaken because strong discrepancies exist between the different $\nu_{6}$ band intensities which are presently available in the $literature^{a b}$. The method which was used in the present work is to use Fourier transform spectra of $H_{2}O_{2}$ recorded at Giessen in a spectral range $(370-1270cm^{-1})$ which covers both the R-branch of the torsion-rotation band at low wavenumber and the P-branch of the $\nu_{6}$ band at high wavenumber. $\bullet$ From the low wavenumber data, the partial pressure of $H_{2}O_{2}$ present in the cell during the recording of the spectra was determined by calibrating the observed absorptions in the torsion-rotation band with intensities computed *** by using the permanent $H_{2}O_{2}$ dipole moment measured by Stark $effect^{d}$. $\bullet$ In the high frequency range, this value of the partial pressure of $H_{2}O_{2}$ was used to measure absolute line intensities in the $\nu_{6}$ band. Finally, the line intensities in the $\nu_{6}$ band were fitted using the theoretical methods described in detail in our previous $works^{a,c}$.
