核磁共振(NMR)谱测量通常采用连续波核磁共振(CWNMR)和脉冲傅里叶变换核磁共振(PFTNMR)两种方法。前者能测量样品的全谱和部分谱,谱线不失真,但灵敏度低;后者灵敏度高,但测量部分谱、避开大溶剂峰等还存在不少问题,并有谱线强度异常现象。Dadok1974年提出了快扫相关核磁共振(RSNMR)方法,其灵敏度接近于PFTNMR方法,又能获得不失真的全谱、部分谱等,成为近十年人们不断探索的一个NMR新方法。它是利用 Nuclear Magnetic Resonance (NMR) spectrometry usually uses two methods, continuous wave nuclear magnetic resonance (CWNMR) and pulsed Fourier transform nuclear magnetic resonance (PFTNMR). The former can measure the full spectrum and partial spectrum of the sample, the spectrum is not distorted, but the sensitivity is low; the latter has high sensitivity, but there are still many problems in measuring the partial spectrum and avoiding the large solvent peak, and there is anomalous spectral line intensity. In1974, Dadok proposed a new NMR method which is close to PFTNMR method and can obtain undistorted full-spectrum and partial spectrum. It has become a new NMR method explored by nearly 10 years. It is to use
