“…In fact, a number of experiments (e.g., matched ESEEM (26,(46)(47)(48)(49)) benefit from the use of tailored nonideal pulses. Consequently, the effect of the nonideality of the pulses should be considered in the simulations (17,50). The time evolution during the extended mw irradiation periods (real pulses) is computed in a frame rotating with the mw frequency about the effective quantization axis of the electron spin.…”
