An iterative algorithm is given to correct for the zeroth and first order phase errors in NMR spectroscopy. A FORTRAN computer program is listed and two sample runs exemplified. No a priori knowledge of the existing phase errors is required. The parameters are optimised iteratively under the assumption that when the spectrum is correctly phased the ratio of the area above the spectrum to that below it is a maximum.
给出了一种迭代算法，用于校正核磁共振波谱中的零阶和一阶相位误差。列出了一个FORTRAN计算机程序，并给出了两个示例运行。无需事先了解现有的相位误差。在光谱正确定相时，光谱上方区域与下方区域的面积比最大这一假设下，对参数进行迭代优化。
