Mössbauer spectra of the iron nitrides have been measured at room temperature and at 550ºC. In the case of the room temperature spectrum of γ´-Fe4N, a fit strategy is reviewed which accounts for two spectroscopically inequivalent iron Fe(1) sites due to the simultaneous presence of magnetic and quadrupolar interactions...
