Hyperfine splitting constant, electron paramagnetic resonance

The N//-azaindole 40 with X = 6 is paramagnetic. Its electron spin resonance (ESR) spectrum (in DMSO) shows a characteristic triplet with a 1 1 1 intensity and the hyperfine splitting constant An = 16.04 Oe. [Pg.234]

ENDOR = electron nuclear double resonance EPR = electron-paramagnetic resonance ESR = electron-spin resonance NMR = nuclear magnetic resonance MA = modulation amplitude SOFT = second-order perturbation theory s-o = spin-orbit zfs = zero-field splitting (for S > 1/2) D = uniaxial zfs E = rhombic zfs g =. g-factor with principal components g, gy, and g ge = free electron g-factor a = hyperfine splitting constant A = hyperfine coupling constant for a given nucleus N (nuclear spin / > 0).
