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.
