    Studies of photoinduced molecular dynamics using ion imaging and correlation analysis by McManus, JW

    Published 2024
    “…A photochemical process of particular interest is the rapid multiple ionisation of a molecule in an intense laser field that causes dissociation into many fragment ions, known as a Coulomb explosion. One of the main topics of this thesis is how the laser-induced Coulomb explosion of a target molecule can be used to characterising its atomic structure, including being able to track structural change following photoexcitation.…”

    Multi-mass velocity-map imaging studies of photoinduced and electron-induced chemistry by Vallance, C

    Published 2019
    “…Multi-mass detection capabilities have also led to the development of two new tools for the chemical dynamics toolbox, in the form of Coulomb-explosion imaging and covariance-map imaging. These allow details of molecular structure to be followed in real time over the course of a chemical reaction, offering the tantalising prospect of recording real-time ‘molecular movies’ of chemical dynamics. …”
