Spectral features of atomic magneto optical rotation spectroscopy the atomic faraday effect and zeeman splittings of various elements

, : Spectral features of atomic magneto optical rotation spectroscopy the atomic faraday effect and zeeman splittings of various elements. Spectrochimica Acta Part B Atomic Spectroscopy 36(11): 1097-1120

Spectral features of atomic magneto-optical rotation spectroscopy (AMORS) or the atomic Faraday effect of various elements are described [for use in trace analysis]. As a stable atomizer, an air-hydrogen flame is located between the pole pieces of the electromagnet. The dependence of the transmitted intensity on the magnetic field strength was recorded on an X-Y recorder by scanning the magnetic field. For most of the analytical lines of elements, the maximum energy was transmitted through the optical system in the Faraday configuration at magnetic field strengths of up to a few kilogauss. The theoretically calculated Zeeman splitting patterns are successfully related to the experimental results.
