摘要：
Rotating frame zero quantum or long-lived coherences among singlet-triplet states in two weakly coupled protons are known to have longer lifetimes than Zeeman magnetization. The usual method for measuring these lifetimes involves fitting a damped oscillatory function, which is lengthy and ineffective for various NMR studies and in turn restricts its usefulness. Here, we introduce a new robust strategy to overcome this problem.
