Conclusion and Outlook
The relaxation behaviour of model systems was characterised for both CP and Uhrig-type pulse sequences of constant sequence length. Despite better suppression of coherence losses for an Uhrig setup in Q-band relaxation measurements, this advantage did not translate into corresponding DEER measurements as 9-pulse DEER experiments were not realisable due to pump pulse inversion inefficiency. At X band signal loss due to destructive interference of frequencies introduced by nuclear modulation leads to an overall better performance of CP-type decoupling with respect to asymmetric Uhrig-type schemes.
