摘要：
An approach for the analysis of magic-angle-spinning NMR spectra which combines nonlinear iterative and linear analytical procedures for fitting sideband spectra is presented. Parameter values, as well as statistical errors, are extracted from the experimental data. The method is particularly useful for the analysis of spectra with limited sensitivity or overlapping lines, and the fitting procedure ensures the highest possible speed. Experimental examples for the analysis of spectra with sidebands due to chemical-shift anisotropies and heteronuclear dipolar interactions are shown. The importance of statistical and systematic errors is considered. © 1991.
