Electron Spin Echo and Coherence Times in Silicon Carbide. Comparison of 250 MHz electron spin echo and continuous wave oxygen EPR. EOF. Quantum pyramid. Electron Spin Echo Envelope Modulation. A theoretical description is presented of the use of electron spin echo spectroscopy to study the spin-correlated radical pairs encountered in photosynthetic systems. Electron spin echo methods allow photosynthesis researchers to probe the local structure of paramagnetic transition metal and organic radical centers. In particular the electron spin echo methods of electron spin echo envelope modulation (ESEEM) and electron spin echo — electron nuclear double resonance (ESE-ENDOR) are used to measure nuclear spin.
Welcome | Core Facilities.
Electron spin echo (ESE) EPR spectra were recorded by means of field-swept two-pulse echo sequence [pi]/2-[tau]-[pi] with the pulse length of [pi] pulse of 12 ns and time delay r = 240 ns. The dependence of the kinetics of electron spin echo amplitude decay on increase of delay time between the microwave pulses is presented in Figure 3.
