| Abstract: | The selective excitation NMR technique with Gaussian soft pulse has been used to record one-dimensional antiphase magnetization spectrum. The antiphase spectrum can be employed further toaccurately measure J coupling constant by combining J - Doubling method. This measurement ofJ coupling constant is suitable particularly for overlapping multiplets and those with large spectrallinewidth and small coupling splitting. |
