My research explores spectroscopic and computational interrogation of the electronic and structural nature of molecules.<\/p>\n

Using a number of spectroscopic techniques including Raman, we identified linker effects which turn off and on electronic communication in donor-acceptor dyes (Barnsley et. al.<\/em>, ChemPhotoChem<\/em> 2017<\/strong>). Further methods of modulating these interactions have been studied (Larsen et. al.<\/em>, Eur. J. Org. Chem.<\/em> 2017<\/strong>, Barnsley et. al.<\/em>, J. Phys. Chem.<\/em> A. 2016<\/strong>). More recently, \u2018dual-emission\u2019 behaviours has been identified in these systems and show sensitivity to the surrounding environment (Barnsley et. al., J. Phys. Chem A.<\/em> 2018<\/strong>). We have also applied Raman spectroscopy to parrot pigments and identified a unique solid state \u2018frequency dispersion\u2019 effect which had not previously been documented (Barnsley et. al., Royal Soc. Open Sci<\/em> 2018<\/strong>). Our computational methods identified that conformational changes may tune the pigments optical properties, which could provide an explanation for this \u2018frequency dispersion\u2019 (Barnsley et. al.<\/em> SciX 2016<\/strong>). Calculations have also been useful when investigating a number of systems such as \u2018inorganic \u2018cages\u2019 (Preston et. al<\/em>. J. Am. Chem. Soc. 2016<\/strong>), \u2018molecular machines\u2019 (Scottwell et. al.<\/em> ChemComm 2017<\/strong>) and \u2018ionophores\u2019 (Lisak et. al.<\/em> Synth. Met. 2016<\/strong>).<\/p>\n
