Question: The corrector Zeeman: 
 Options:  <1> It is widely used in Molecular Fluorescence to correct the internal filter effect. <2> It is a basic corrector in atomic absorption spectrometry, which is based on the property that atoms have in the form of atomic vapor of unfolding their electronic energy levels when subjected to an intense magnetic field, originating different emission lines for each transition electronics. <3> It is based on the phenomenon of self-absorption that occurs when the hollow cathode lamp is subjected to high currents and is widely used in atomic absorption spectrometry. <4> It is based on the emission of continuous radiation in the ultraviolet region of a deuterium lamp, used as a background corrector. <5> It is a corrector of chemical interferences, widely used in atomic emission spectrometry.
