J-Modulation in ID NMR ¹H Spectrum of Taurine and Aspartate Using Spin-Echo Technique

Abstract

This study reports on a theoretical calculation of Hahn's spin-echo experiment in case of a model A 2 Bt spin system with a strongly coupling character and gives the experimental results of one-dimension n H high-resolution NMR spectra of taurine and aspartate. The calculated amplitudes of the spinechoes for two different proton groups of taurine are given. Using results of our calculations for taurine, the computer simulations of /-modulation are implemented. It is shown that the agreement between the experimental and simulated spectra is good.
