A spectral simulation method is described for generating a priori information for use in parametric spectral analysis. The method makes use of GAMMA (S. A. Smith, T. O. Levante, B. H. Meier, R. R. Ernst, J. Magn. Reson., 106A, 75-105, 1994), a programming environment that facilitates simulation of magnetic resonance phenomena. The input parameters consist of the chemical shifts and scalar spin-coupling constants for the compounds to be analyzed, the acquisition pulse sequence, and the field strength used. The resultant spectral information consists of the relative amplitude, frequency, and phase of all resonances, which are stored in a spectral database. This procedure can be rapidly and conveniently modified to reflect different acquisition parameters and data analysis requirements.
描述了一种光谱模拟方法，用于生成用于参数光谱分析的先验信息。该方法利用了GAMMA（S.A.史密斯、T.O.莱万特、B.H.迈尔、R.R.恩斯特，《磁共振杂志》，106A，75 - 105，1994），这是一个便于模拟磁共振现象的编程环境。输入参数包括待分析化合物的化学位移和标量自旋耦合常数、采集脉冲序列以及所使用的场强。所得的光谱信息包括所有共振的相对幅度、频率和相位，这些信息存储在光谱数据库中。此过程可以快速方便地修改，以反映不同的采集参数和数据分析要求。
