The Ennis group is interested in the application of laboratory infrared spectroscopy (including cryogenic thin-film FTIR, matrix isolation, synchrotron far-IR and THz, and aerosol scattering techniques), to characterise crystalline solids.
These investigations are often performed in the context of solid-state astrochemistry, molecular crystals, and supramolecular gas sorption studies where information on UV photochemistry, crystal morphology, and intermolecular interactions within the bulk material to be gathered.
These infrared techniques are coupled with periodic DFT frequency calculations for characterisation of many physicochemical properties of the crystal-phase.
