Janne Marie Soetbeer determines the optimal dynamical decoupling (DD) scheme for efficient reduction of electron spin coherence loss in model systems for spin labelled biomolecules depending on their particular relaxation behavior. Extending the nth order DD scheme to double electron-electron resonance (DEER) experiments require the addition of multiple pump pulses for ≠ 1. Incomplete excitation of pump spin packets introduce signal artefacts which are minimized by pump pulse optimization including linear-chirp and asymmetric hyperbolic secant pulses. Prolonging the dipolar evolution time with decreased signal artefact allows to extent the measurable interspin distances in biomolecules which were otherwise not accessible due to spin echo relaxation.

After a research stay with Prof. Dr. Robert Griffin at the Massachusetts Institute of Technology in Cambridge, USA, she will be returning to Zurich to start her PhD in Prof. Dr. Gunnar Jeschke's group.
