Embodiment Construction
[0050] Below in conjunction with accompanying drawing and embodiment, the present invention will be further described:
[0051] In this embodiment, a Varian 500 MHz magnetic resonance instrument equipped with a three-dimensional gradient field is used, and the sample is a 1:1 mixed solution of ethyl tribromopropionate and butanone. The pulse sequence used is as Figure 1~3 shown.
[0052] The inhomogeneity of the magnetic field is achieved by adjusting the Z1 shim coil in the Z direction. Under such an inhomogeneous magnetic field, the traditional monopulse sequence is as follows: Figure 8 The low-resolution spectrum of the spectral line broadens and aliases, and the lines and centers of the spectral lines cannot be identified from the spectrogram. Using the LBI-1 sequence in the present invention, such as figure 1 As shown, the applied disturbance gradient strength is 0.0586 Gauss / cm, throughout the entire free evolution time (t 1 ). The sampling digital resolution of ...
