Analyzing reaction rates with the distortion/interaction‐activation strain model

FM Bickelhaupt, KN Houk - Angewandte Chemie International …, 2017 - Wiley Online Library
The activation strain or distortion/interaction model is a tool to analyze activation barriers that
determine reaction rates. For bimolecular reactions, the activation energies are the sum of …

The activation strain model and molecular orbital theory: understanding and designing chemical reactions

I Fernández, FM Bickelhaupt - Chemical Society Reviews, 2014 - pubs.rsc.org
In this Tutorial Review, we make the point that a true understanding of trends in reactivity (as
opposed to measuring or simply computing them) requires a causal reactivity model. To this …
