  • Method for acquiring NMR phase-sensitive 2D J-resolved spectrum by suppressing strong coupling spurious peaks
    Patent number: 11650274
    Abstract: A method for acquiring nuclear magnetic resonance (NMR) phase-sensitive two-dimensional (2D) J-resolved spectrum by suppressing strong coupling spurious peaks, comprising: 1) placing a sample, collecting a conventional one-dimensional (1D) spectrum of the sample, and measuring a time width (pw) of a 90° pulse, wherein the conventional 1D spectrum provides J coupling information and chemical shift information of the sample; and 2) introducing a pulse sequence for suppressing strong coupling, setting parameters of a chirp sweep frequency pulse, a pure shift yielded by chirp excitation (PSYCHE) module, and a J sampling module, and collecting and saving data of a spectrum.
