Summary:Factor analysis has been used to deduce the composition of multicomponent magic angle spinning NMR spectra comprised of overlapping isotropic peaks. The technique has been used to determine the number of constituents present and was combined with a target transformation minimization procedure to identify the component MAS spectra. The new analysis procedure is compared to the conventional least-squares approach and is found to be superior in all cases.
