Non-Lorentzian diffusion-broadened Mossbauer lines are reported for two different systems: (i) SnO, particles in silicon grease; and (ii) Fe(C,H,O,), dissolved in 1,3-propanediol. Both results are discussed as superpositions of Lorentzians each representing a particular situation of a Mossbauer nucleus. A model for the interpretation of the SnO, result is presented. Agreement is found assuming that rotational diffusion of the SnO, particles is dominating.
