✦ Synopsis


If the basic profile shapes of the normal Zeeman triplet do not have zeros in their Fourier transform, the magnetic field splitting can be determined independent of the profile shape, When the ratio of the splitting of the components is greater than the intrinsic FWHM of the component profiles the magnetic splitting can be determined with significantly greater accuracy than the measurement accuracy of the original profile. For Gaussian shaped components and a ratio of magnetic splitting to FWHM of 1.5 the noise reduction factor is 25.
