WebIntrinsic reaction coordinates (IRCs) can be determined a number of ways (a discussion of these methods lie way outside the scope of this post). Suffice to say, the reaction pathway is an 'energy' pathway of reaction, connecting reactants and products, usually through some intermediate and/or transition state (TS). WebVibrational frequency analyses along with intrinsic reaction coordinates calculations showed that such transition states belong to the pathway of nucleophilic attack by the …
