Abstract
A pulse sequence method for realizing selective detection of multiple groups and/or molecules by simultaneously preparing nuclear spin singlets and/or singlet orders of the multiple groups and/or molecules. Taking an AGG molecule as an example, it is proposed to simultaneously prepare two pairs of uncoupled group signals of the AGG molecule into nuclear spin singlets and/or singlet orders, and eliminate magnetic resonance signals other than the nuclear spin singlets and/or singlet orders by using a pulsed gradient field, thereby realizing simultaneous selective observation of multiple group signals in the AGG molecule. Also disclosed is a method for simultaneously detecting group AGG-A in an AGG molecule and group Tau-C and group Tau-D in a Tau molecule. For the first time, the simultaneous preparation and signal selection of multiple nuclear spin singlets and/or singlet orders in a spin system is achieved. Compared with the conventional method, this method has higher sensitivity and better selectivity, and can further expand the application range of magnetic resonance.
