UNIVERSITY OF AARHUS, Department of Physics and Astronomy PhD Scholarship in Molecular Physics At the Faculty of Science two PhD scholarships are offered within the area of Molecular Physics. The PhD scholarships are to be filled by 1 October 2007 or as soon as possible thereafter. The PhD scholarships are a part of a project on ‘the photophysics of gas- phase chromophore ions’ under the supervision of Professor Lars H Andersen. If you are awarded a scholarship you are expected to participate in the PhD programme and attain a PhD degree. It is therefore a condition for employment that the applicant is approved for enrolment as a PhD student at the Faculty of Science, University of Aarhus. Your salary and further terms of employment are governed by the agreement between the Danish Ministry of Finance and the Danish Confederation of Professional Associations (Akademikernes Centralorganisation). The project Experiments will be carried out with state-of-the-art equipment at the University of Aarhus, such as the storage ring ELISA and fs-lasers. The goals are: • to elucidate the absorption characteristics of isolated molecular ions in vacuo and study how the electronic structure is perturbed by a chemical environment, e.g. a solvent or protein interior • to explore the dynamics and kinetics of photo-dissociation processes by using short laser pulses. The interplay between light and molecules, both neutral and ionic, is fundamental in nature and materials science: photosynthesis, vision, signal transduction, fluorescent proteins, DNA photodamage, optical devices - just to mention a few important cases. The part of the molecule that interacts with the light is denoted the chromophore, and its absorption spectrum depends on the surrounding chemical environment, for example a solvent or protein interior. We study the photophysics of isolated systems (the gas phase) to understand the complicated molecular perturbations that are found in different environments. Color vision, for example, is made possible only because of such perturbations. We have developed state-of-the-art instruments at the University of Aarhus that have put us at the forefront when it comes to addressing the electronic structure of macromolecular ions, in particular bio-chromophores. Currently, chromo¬phores are being studied both experimentally and theoretically in collaboration with the Chemistry Department and foreign institutions. Application procedure Please attach your CV, a motivation for your application, complete official transcripts from colleges or universities including the grades, and up to three letters of recommendation (max. 1 page/letter).
