Reaction kinetics and dynamics


Reaction kinetics and dynamics refers to the study of why, how and how fast chemical processes take place. Chemists seek to understand the details of change at the molecular and quantum level and how such reactivity can be affected, pushing the boundaries of technology and theory to do so.

    Ejecting electrons from negative ions using light can create structures that very closely resemble the transition states of bimolecular reactions. Now, using this technique, trapped quantum states, or 'resonances', have been observed in a seven-atom reaction, and theory has been shown to be up to the task of capturing such complex phenomena.

    A detailed picture of how DNA is copied and modified comes from a molecular-level understanding of DNA and the enzymes that process it. Why is DNA not always copied correctly, and what happens when its bases are modified?

    Controversy surrounds the perceived absence of a relationship between DNA polymerase fidelity (kinetic discrimination) and free energy changes determined from DNA melting studies (thermodynamic discrimination). Thermodynamic discrimination together with aqueous solvent effects can account for kinetic fidelities on the order of those observed experimentally.

    Femtochemistry, the real-time study of reactions on a timescale that captures the molecular and atomic activity involved, has traditionally been performed in the gas or liquid phase. It has now been extended to the solid state in a study that highlights how a controlled reaction environment can place steric constraints on the motions of photoproducts.

    Spin-triplet excitations commonly migrate through direct electron exchange between neighbouring molecules. Now, experiments show that back-and-forth interconversion between spin-triplet and spin-singlet states can significantly speed up triplet migration in organic crystals.
