| 摘 要： | The ~(13)C-~1H long-range coupling constants of β-pyridine carboxylic ester are determined with the method of folding of two-dimensional NMR J spectroscopy and prove consistent with their simulated spectra. The modified computer program which can shorten the experimental time of heteronuclear two-dimensional J spectroscopy and improve the work is introduced. The experiment is performed on the Varian FT-80A NMR spectrometer.
