| contents | The overall goal of this thesis is to investigate the connection between the dynamics and structure of molecular glass formers, by testing different scaling laws for both. The inspiration for this work is the Isomorph theory because it predicts a connection between structure and dynamics. The fundamental prediction of the Isomorph Theory is that there exist lines in the phase diagram where both structure and dynamics are invariant when presented in reduced units. The prediction of constant dynamics has been tested and confirmed experimentally several times, but the structural prediction has never been confirmed experimentally. In this thesis, we have investigated the structural prediction for liquids where the prediction of constant dynamics has been shown experimentally. |
