Reaction mechanisms are the step-by-step pathways by which chemical reactions occur, involving the breaking and formation of chemical bonds. Understanding reaction mechanisms is essential in chemistry as it helps predict the outcome of a reaction and guide the design of new reactions. Researchers study reaction mechanisms through various experimental techniques such as spectroscopy, kinetics, and theoretical calculations. This research area aims to elucidate the detailed molecular processes that occur during a chemical reaction, providing valuable insights into the nature of chemical interactions and the underlying principles of chemical reactivity.
