Abstract
Two types of selective detection of paramagnetic species, based on Zeeman effect, have been examined with both Fourier transform and diode laser spectrometers. A magnetic modulation requires both a constant and a periodic magnetic fields: however a variation of the magnetic field in a plasma induces, in addition to Zeeman modulation, a non selective modulation concentration. This effect is avoided with a polarization modulation which needs a polarizing system and a constant magnetic field only. We present here experimental results obtained using these technics.
