Embodiment Construction
[0023] The following embodiments will further illustrate the present invention in conjunction with the accompanying drawings:
[0024] A phase-sensitive and selective J spectrum method for suppressing axial peaks described in the embodiment of the present invention, the main steps are:
[0025] 1) collecting the NMR one-dimensional spectrum of the sample;
[0026] 2) Measure the pulse width of the 90-degree hard pulse of the sample;
[0027] 3) Determine the range of hydrogen spectrum that needs to be analyzed;
[0028] 4) Take the frequency of the S nucleus to be measured in the hydrogen spectrum as the excitation center of the selectively excited 180-degree soft pulse, set the power and time of the selectively excited 180-degree soft pulse, and set the dephase gradient G 1 ;
[0029] 5) Take the central frequency of the hydrogen spectrum to be analyzed as the excitation center of the hard pulse, and set the power and time of the 90-degree and 180-degree hard pulse;
