Mass-independent fractionation (MIF) is a process that causes isotopes of an element to be distributed in a way that is not solely dependent on their mass. This phenomenon often occurs in specific chemical reactions or under certain environmental conditions, particularly in relation to non-standard isotopic processes. MIF is particularly well-documented in the context of certain elements, such as sulfur, oxygen, and mercury.
