A convenient and accurate method for the measurement of the values of spin-spin coupling constants

摘要: Abstract A method is introduced which makes it possible to measure, reliably and accurately, values of scalar coupling constants from spin multiplets, even in situations where no splittings are resolved. The assumptions about the lineshapes individual component lines multiplet, does not involve a multiparameter fit, nor rely on subjective criteria; can be applied multiplets range unmodified experiments. expected accuracy con stants determined by depends primarily signal-to-noise ratio spectrum, linewidth, certain other deviations spectra analyzed an assumed ideal. effect each these factors considered quantitatively. Finally, illustrated using analyze different kinds spectra.
