Gd(III)–Gd(III) distance measurements with chirp pump pulses
TL;DR: Frequency-swept chirp pulses are utilized as pump pulses in the DEER experiment to balance modulation depth and echo intensity for optimum sensitivity, and larger sensitivity is anticipated for Gd(III) complexes with zero-field splitting that is smaller than for the employed Gd-PyMTA complex.

Perspectives of shaped pulses for EPR spectroscopy.
TL;DR: Current uses of shaped pulses, generated by an arbitrary waveform generator, in the field of EPR spectroscopy are described and a procedure to correct for experimental imperfections is described.
Journal ArticleDOI
Sensitivity enhancement by population transfer in Gd(III) spin labels
TL;DR: In order to enhance echo signals observed with selective pulses, equilibrium populations of the energy levels of S = 7/2 Gd(III) spin labels are rearranged with frequency-swept passage pulses and a dipolar modulation depth of 9% is demonstrated, which results in an enhancement of 3.3 with respect to data obtained with monochromatic rectangular pulses.

Wideband frequency-swept excitation in pulsed EPR spectroscopy
Andrin Doll,Gunnar Jeschke +1 more
TL;DR: Based on the bandwidth limitations that arise from spin dynamics, requirements are derived for a spectrometer that achieves precise spin control over wide bands and the design of such aSpectrometer and hardware characterization by EPR experiments are discussed.

Broadband spin echoes and broadband SIFTER in EPR.
TL;DR: A broadband Hahn, stimulated and refocused echo sequence derived from adiabatic pulses is presented, a solid echo based pulse sequence to measure the dipolar coupling between two unpaired electron spins and an artifact free dipolar evolution time trace is achieved in the SIFTER experiment.

The signal-to-noise ratio of the nuclear magnetic resonance experiment
D.I Hoult,Rex Edward Richards +1 more
TL;DR: A fresh approach to the calculation of signal-to-noise ratio, using the Principle of Reciprocity, is formulated, to give the same results as the traditional method of calculation, but its advantage lies in its ability to predict the ratio for other coil configurations.

The Return of the Frequency Sweep: Designing Adiabatic Pulses for Contemporary NMR
Michael Garwood,Lance DelaBarre +1 more
TL;DR: The classical adiabatic rapid passage is analyzed using vector models in different rotating frames of reference and ways to tailor modulation functions to best satisfy specific experimental needs are demonstrated.
