Behavior of two almost identical spins during CPMG pulse sequence

Original language description

Multiple-spin-echo experiments have found wide use in nuclear magnetic resonance spectroscopy. In particular, the Carr-Purcell-Meiboom-Gill (CPMG) pulse sequence is used to determine transverse relaxation times T2. Herein it is demonstrated, both theoretically and experimentally, that for a pair of almost identical spins-1/2 the experimental setup can have a profound effect on the observed spin dynamics. It is shown that, in the case of dipolar relaxation, the measured T2 values can roughly vary betweenthe limits of identical and unlike spins, just depending on the repetition rate of pulses with respect to chemical shift separation. Such an effect can, in the extreme narrowing regime, amount to a 50 % difference.
