Nettet6. mai 2010 · First, we have the natural line width limitation imposed by the T2 (spin-spin relaxation). For example, if T2 is about 1 second, the peak linewidth at half height … NettetThis is the reverse of how NMR experiments are typically performed, where the magnetic field is held constant while the radio frequency is varied. Due to the short relaxation times of electron spins in comparison to nuclei, ... the resonance line width (ΔB) can be written as \[\Delta B\propto \dfrac{1}{T_{1e}}+\dfrac{1}{T_{2e}} \label{53}\]

If the two species are in equilibrium and exchange to each other, peaks of both species get broadened in the spectrum.
NettetJustifying from the different ESR linewidths, the spectrum can be regarded as an overlap of two sets of signals. One is a wide triplet with nitrogen hyperfine coupling of AN = 13.8G at g = 2.0067. And another is a quintet with A N = 6.6G, which is attributed to the coupling of two nitrogen nuclei with the unpaired electron. NettetExperimental observations of the residual homogeneous line width as a function of spinning frequency show that it can often be approximated by a linear correlation with the inverse of the spinning frequency with some deviation that indicates a partial inverse quadratic dependence ( Nishiyama , 2016; Sternberg et al. , 2024; Penzel et al. , 2024; …
