Research Profile

The research interests of the Riley group are centred on probing the electronic structure and bonding of inorganic complexes. This covers a very broad range of experimental and theoretical techniques. Molecular spectroscopy is capable of providing information about both the electronic structure and bonding in both the ground and excited electronic states.

Some of the experimental techniques used are:
low temperature (10K) polarised single crystal absorption (UV-Vis-IR), circular dichroic, Stark, time resolved fluorescence, excitation and Raman spectroscopies.
