Spectral lines, probing rotational quantum states J'=0,1,2 of the inner well vibrations (v' =< 8) in the BB" 1Su+ state of molecular hydrogen, were recorded in high resolution using a vacuum ultraviolet (VUV) Fourier transform absorption spectrometer in the wavelength range 73-86 nm. Accurate line positions and predissociation widths are determined from a fit to the absorption spectra. Improved values for the line positions are obtained, while the predissociation widths agree well with previous investigations.
