The TROSY experiment ( 97PNAS12366 , 00QRB161 and 03COP570 ) selects only one of the four possible cross peaks belonging to an IS spin system in a F1,F2-coupled 1H-X correlation experiment.

The TROSY approach has been successfully implemented in many double- and triple-resonance 2D/3D/4D TROSY-like experiments
