This is a PhD research project in experimental Physics. It will employ ultrafast femtosecond lasers in conjunction with novel hollow-core photonic crystal fibre sources to undertake state-of-the art time-resolved photoelectron imaging measurements investigating non-radiative energy redistribution in UV excited molecules. The systems chosen will provide analogues of the chromophores (i.e. the light absorbing centres) found in larger molecules of biological significance. A key focus will be on the interplay between molecular structure, dynamical timescales and photochemical function. The project will develop advanced skills in non-linear optics, lasers, molecular spectroscopy and ultrahigh vacuum techniques. Some software development for data acquisition/analysis will be required and there will also be opportunities to gain proficiency with commercial quantum chemistry computational platforms such as Gaussian.
