• N donor atoms. Conventional ESR experiments do not allow for obtaining such information. The pulse Davies ENDOR technique is based on the detection of the electron spin echo (ESE) [34][39]. The microwave (mw) pulse sequence of this technique consists of three pulses π–τ–π/2–τ–π–ESE that define three

• SCRPs, whereas Lukina et al. [120] have recently reported a study of the out-of-phase electron spin echo. Until now, no CIDNP phenomenon has been observed in spintronics [121][122][123][124], although the possibility of obtaining such effects has been mentioned [125]: “If nuclear spin resonance is found

• . Keywords: electron spin echo; ESR; hyperfine interaction; molecular complexes; spin coherence; Introduction Cu(II)−(bis)oxamato and Cu(II)−(bis)oxamidato complexes have attracted in the recent past substantial attention as precursor materials for the synthesis of the corresponding polynuclear complexes

• the excitation of the forbidden transitions induced by the microwave pulses which produce the electron spin echo signal, so that allowed and forbidden ESR transitions manifest the coherence in their excitation by the microwave pulses. This spin coherence is manifested as the ESEEM effect [29][30][31

• scale 10−4–10−5 s. Thus, the shift of the ESR frequency of the electron spin is a stochastic process ω(t). A stationary distribution of these frequencies determines the HF structure of an ESR spectrum. The theory in [30][33][38] shows that the primary electron spin echo signal decay resulting from the
