Rotational Structure in the 21.22 eV Photoelectron-Spectrum of H2: The form of the vibrational steps in the 21.22 eV potoelectron-Spectrum of H2 was analysed using a retarding field electron energy spectrometer with 10 meV resolution and a computer programme for a least squares fit analysis. Even though the broadening caused by the thermal motion of the H2 molecules during the photoionization process prevented the complete resolution of the rotational structure, it is possible to conclude from the results that the angular momentum of the nuclear rotation does not change in the photoionization process of H2 molecules with 21.22 eV photons.
