Short summary
Quantification of heterogeneous systems such as unstructured or semi-structured (bio)macromolecules is an important but challenging task. Pulse EPR methods can contribute by characterizing the local nuclear environment of a spin centre. Here, we provide a detailed assessment of a pulse EPR technique derived from a RIDME experiment. We review the theoretical principles, discuss the data analysis and demonstrate an application to a spin-labeled macromolecule supported by in silico modelling.

Short summary
Sensitivity is often a limiting factor in electron–nuclear double resonance (ENDOR). Here we demonstrate how using chirp radiofrequency pulses can improve ENDOR sensitivity up to 3–9 fold, with the strongest increase for broader lines often encountered in disordered solids for nuclei such as nitrogen and metals. The resulting drastic speedup in acquisition times also renders 2D ENDOR more feasible, as we demonstrate in TRIPLE, showing correlations with Cu hyperfine couplings.

Short summary
Electron spin dynamics during microwave irradiation are of increasing interest in electron paramagnetic resonance (EPR) spectroscopy. Here, we show that these dynamics can be probed by modern pulse EPR experiments that use shaped microwave pulses. Combined with spin dynamics simulations, these results provide a starting point for optimizing existing EPR experiments and for developing new pulse sequences.

Nanometre distance measurements between spin labels by pulse EPR techniques yield structural information on the molecular level. Here, backed by experimental data, we derive a description for the total signal of the single-frequency technique for refocusing dipolar couplings (SIFTER), showing how the different spin–spin interactions give rise to dipolar signal and background – the latter has thus far been unknown.

Short summary
Dynamic nuclear polarisation (DNP) transfers polarisation from electron to nuclear spins. This is usually combined with direct detection of the latter. Here, we show that it is possible to reverse the transfer at 1.2 T. This allows us to investigate the spin dynamics of nuclear spins close to electrons – something that is notoriously difficult with established methods. We expect reverse DNP to be useful in the study of spin diffusion or as a building block for more elaborate pulse sequences.

Short summary
With a pulsed dipolar electron paramagnetic resonance technique named double electron–electron resonance (DEER), we measure nanometer distances between spin labels attached to biomolecules. If more than one spin type is present (A and B), we can separately address AA, AB, and BB distances via distinct spectroscopic channels, increasing the information content per sample. Here, we investigate the appearance of unwanted channel crosstalks in DEER and suggest ways to identify and suppress them.

Short summary
Resonant pulses in a spin-lock frame are used to select parts of the rf-field distribution in NMR experiments. Such pulses can be implemented in a straightforward way and arbitrarily shaped pulses can be used. We show an application of such pulses in homonuclear decoupling where restricting the amplitude distribution of the rf field leads to improved performance.

Short summary
Measuring distances between unpaired electron spins is an important application of electron paramagnetic resonance. The longest distance that is accessible is limited by the phase memory time of the electron spins. Here we show that strong continuous microwave irradiation can significantly slow down relaxation. Additionally, we introduce a phase-modulation scheme that allows measurement of the distance during the irradiation. Our approach could thus significantly extend the accessible distances.

Short summary
Light-induced pulsed dipolar EPR spectroscopy (PDS) is an emerging field that uses photoexcited triplet states to determine distance restraints in the nanometer range. To date, light-induced PDS data have been analyzed with methods developed for techniques that do not invoke light-induced triplets. Here, we provide a new theoretical description that takes the full nature of the triplet state into account and demonstrate that it leads to more accurate fits of experimental data.

Short summary
Electron spins sense their environment via magnetic interactions. An important contribution stems from nuclear spins in their vicinity. They cause loss of coherence and thus reduce resolution of spectra obtained by experiments on electron spins and the efficiency of transferring electron-spin magnetization to other nuclear spins. Here we study how protons in trityl radicals contribute to coherence loss. Such coherence loss is slower in the presence of a strong microwave field.
