Fano profiles are omnipresent in atomic spectra. They are caused by interference between two channels evolving to the same final state. and therefore carry intricate information about the underlying electronic rearrangements in time. For electronic decay processes in molecules, however, these signatures are washed out. Amongst others, the famous example of the combined autoionization and photo-dissociation spectra of the hydrogen molecule shows no Fano profiles, neither in experiment, nor in simulations including unclear motion [1]. We discuss this phenomenon for different model potentials and experimental conditions, and thereby reveal under which conditions a peak structure can be observed. [2]
