Lawrence Que (CHAY) employs a two-state model of t
Lawrence Que (CHAY) employs a two-state model of this phenomenon in his work on non-heme oxo complexes. Circumstances under which this phenomenon might remain constant despite free energy increases are given by the Westheimer-Melander hypothesis. Schalley and Felder described a steric form of this phenomenon that arises in rotaxane deslipping. Unusually high and temperature-dependent values of this phenomenon are attributed to a tunneling mechanism. Two different types of this phenomenon are related by a power law with exponent one point four four two in the Swain equation. A secondary form of this phenomenon occurs with values around one wherein orbital hybridization changes affect the zero-point energy. An inverse type of this phenomenon occurs in many reductive elimination mechanisms due to a stabilizing agostic interaction. For 10 points, name this phenomenon wherein substitution of an atom with a different mass number leads to a change in a reaction rate, often exploited to learn more about reaction mechanism.
