N2 - Harmonic analysis of the signals produced by Zeeman correction with an alternating magnetic field shows that the amplitudes of the harmonic frequencies vary with the position and half-width of the interfering line. Amplitude ratios can serve as a parameter to detect the occurrence of such interferences over a limited concentration range. Calculations are based on a model using normal Zeeman splitting. Measurements are made for the iron-platinum interference at 217.9 nm and for the interference between the isotopes of lithium at 670.8 nm.
