Electronic Raman spectra in iron-based superconductors with two-orbital model is discussed. In the orbital space, some possible pairing symmetries of the gap are selected. To further discriminate them, electronic Raman spectra and spectra weight at Fermi surface (FS) which helps understand the Raman spectra are calculated in each case. From the low energy threshold, the number of Raman peaks, and the low frequency power law behavior, we can judge whether it is full gap or nodal gap, and even one gap or multi-gaps. The results provide useful predictions for comparison with experiments.
► Electronic Raman spectra were calculated in orbital space in a microscopic theory.
► Both Raman spectra and spectra weight were presented.
► Raman spectra for the gap symmetries are different from each other.
► The results can help decide the gap symmetry by comparing with experiments.
