Eoghan spoke this week at the 691st WE Heraeus Seminar this week. The meeting was held in Physik-Zentrum in Bad-Honnef near Bonn and was entitled “Physical Organic Chemistry: Recent developments in instrumentation, structure, theory, and mechanisms”. The meeting was organised by Prof. Christina Thiele (TU Darmstadt) and Prof. Peter Schreiner (Uni. Giessen) and had great talks from across the breadth of physical organic chemistry. Some of our highlights were talks by Profs Peter Chen (ETH Zurich), Ruth Gschwind (Regensberg), Derek Pratt (Ottawa), Steve Fletcher (Oxford) and Dan Singleton (Texas). There were lots of opportunities to engage with all of the participants at this excellent venue. Thanks to the meeting sponsors, the Wilhelm and Else Heraeus Foundation, for making this excellent meeting possible.
