Apodization weighted acquisition is a simple approach to enhance the sensitivity of multidimensional NMR spectra by scaling the number of scans during acquisition of the indirect dimension(s). The signal content of the resulting spectra is identical to conventionally sampled data, yet the spectra show improved signal-to-noise ratios. There are no special requirements for data acquisition and processing: the time-domain data can be transformed with the same schemes used for conventionally recorded spectra, including Fourier transformation. The method is of general use in multidimensional liquid and solid state NMR experiments if the number of recorded transients per sampling point is bigger than the minimum required phase cycle of the pulse sequence.

通过切趾加权采样提高FT-NMR光谱的灵敏度。

变迹加权采集是一种简单的方法，可以通过缩放间接维的获取过程中的扫描次数来增强多维NMR光谱的灵敏度。所得频谱的信号内容与常规采样数据相同，但是频谱显示出改善的信噪比。数据采集​​和处理没有特殊要求：可以使用与传统记录光谱相同的方案（包括傅立叶变换）来变换时域数据。如果每个采样点记录的瞬变数大于脉冲序列的最小所需相周期，则该方法通常用于多维液相和固态NMR实验。
