Short summary
Short summary
We recently liberated the solid effect of dynamic nuclear polarization (DNP) from its perturbative treatment by describing the relevant spin dynamics in a time domain. This allows us to easily account for dynamical processes that modulate the spin interactions in liquids, like the translational diffusion of spins. Here we additionally model the slow rotational diffusion of the polarizing agent and analyze DNP data from nitroxide spin labels in lipid bilayers at 9.4 T.

Short summary
Pulsed electron paramagnetic resonance can measure distances and orientation between two paramagnetic markers. If they are rigidly attached to a biomolecule, advanced insights into the structure and dynamics of the biomolecule follow. We used chirp pulses to perform real two-dimensional experiments with much shorter experimental time compared to experiments with monochromatic microwave pulses. We also present new pulse sequences and give a detailed protocol for setting up such experiments.
