Deadtime Free Echo Modulation in Pulsed EPR
Two different pulse sequences are proposed for measuring echo envelope modulation in pulsed EPR. They alleviate the deadtime problem by detecting the echo’s echo and the spin-locking echo. A stimulated Hahn echo sequence is presented which is composed of two pulses and relates to both the Hahn and stimulated echo sequences. The spin-locking sequence provides also a measure of the spin lattice relaxation time T1p in the rotating frame.
