- To demonstrate the capability of detecting intermolecular spin correlations in solution.
Main Methods:
- Utilized correlated spectroscopy revamped by asymmetric z gradient echo detection (CRAZED).
- Employed magnetic-field gradient pulses to detect correlations between spins in different molecules.
- Tuned spin separation detection range by adjusting gradient pulse areas.
Main Results:
- Successfully detected correlations between spins in different molecules using CRAZED.
- Demonstrated that observable signals require spin separation within a narrow, tunable band.
- Achieved tunable detection of spin separations from sub-10 micrometers to over 1 millimeter.
Conclusions:
