Abstract
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 between the 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.
