Variational transition-state theory

Variational transition-state theory (VTST) is an advanced theoretical framework in chemical kinetics used to study chemical reactions, particularly the rates at which they occur. It builds upon traditional transition-state theory (TST), which describes the formation of products from reactants through a high-energy transition state. Here are key concepts surrounding VTST: 1. **Transition State**: In reaction dynamics, the transition state corresponds to the highest energy configuration along the reaction pathway.
