本文介绍了一种在定量核磁共振波谱学中普遍使用的时域去卷积方法QUALITY。通过将实验NMR时域信号除以参考信号，可以在单独的实验中或经由实验光谱中的孤立单共振的逆傅立叶变换获得参考信号，可以获得完美的洛伦兹线形，而不管磁场不均匀性如何。实验结果表明，该方法具有良好的性能，无论是在实验中使用表面线圈还是在体外使用表面线圈和高分辨核磁共振探针。
A method of time domain deconvolution, QUALITY, is described for general use in quantitative NMR spectroscopy. By division of the experimental NMR time domain signal by a reference signal, which may be obtained either in a separate experiment or via inverse Fourier transformation of an isolated single resonance in the experimental spectrum, perfect Lorentzian lineshapes can be obtained regardless of the magnetic field inhomogeneity. Experiments, bothin vivousing a surface coil andin vitrousing a surface coil and a HR NMR probe, show excellent performance of the method.
