VUV spectroscopic study of the B '' (B)over-bar(1) Sigma(+)(u) state of H-2

Spectral lines, probing rotational quantum states J′ = 0, 1, 2 of the inner well vibrations (υ′ ≤ 8) in the state of molecular hydrogen, were recorded in high resolution using a vacuum ultraviolet 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. © 2014 Taylor and Francis.
