实例分析Hadamard编码技术在高分辨NMR谱技术中的运用

Application of Hadamard Coding in High Resolution NMR Spectroscopy

核磁共振(Nuclear Magnetic Resonance)技术是一种具备无创性、选择性以及高度的灵敏性特点的检测技术,它能表达化学位移、J耦合常数等精细的分子层级的信息,在生物、化学、生命科学等领域得到广泛应用。但由于传统的NMR方法在存在大的不均匀磁场时获取高分辨谱需要花费较长的时间,因此结合Hadamard编解码技术设计新的NMR序列是非常有意义的。

Nuclear magnetic resonance technology(NMR) is a non-invasive, selective and highly sensitive detection technology.It can express fine molecular level information such as chemical shift and J-coupling constant.It has been widely used in the fields of biology, chemistry, life science and so on.However, because the traditional NMR method takes a long time to obtain high-resolution spectrum in the presence of large uneven magnetic field, it is very meaningful to design a new NMR sequence combined with Hadamard codec technology.
