Description
Summary:	In this work we discuss the extension of electron spin-echo envelope modulation (ESEEM) measurements to the additional time dimension, the spin-echo coordinate. The time-resolved acquisition of the entire spin-echo signal shape retains information on the dependence of the ESEEM amplitude on the position within the ESE signal. Therefore, not only can such acquisition be completely substituted for the boxcar integration in ESEEM measurements, but it can also improve the performance of the ESEEM experiments in terms of obtaining correct modulation amplitudes and a better signal/noise ratio. Implementing such an acquisition in pulse-adjustable ESEEM measurements transforms these techniques into routine and convenient experiments used to increase the modulation amplitude.
