An analytical expression describing the dependence of the amplitude of ESE modulation on the intensity of the microwave field has been derived and verified experimentally.
Most electron spin echo (ESE) experiments are performed at X-band ( 4 9 GHz) microwave frequencies. Just as in cw EPR, however, a multifrequency approach to ESE spectroscopy provides a more accurate determination of spin Hamiltonian parameters. The use of lower microwave frequencies (fields) in ESE
The effect of homonuclear J modulation on 19F spin-echo images is evidenced by a substantial reduction in signal when the echo time, TE, approaches 1/2J, with a subsequent increase in signal at longer TEs. Suppression of the J-modulation effect is demonstrated using chemical shift-selective 180 degr
