Polarized optical spectroscopy magnetic fields

Figure 3 The Faraday Effect within magnetic optical rotatory dispersion (MORD) spectroscopy. A plane polarized beam is rotated by a magnetic field applied parallel to the axis of propagation. The rotation is defined as positive if the beam is rotated to the right in a clockwise direction when viewed toward the source (a). The original definition of Icp and rep within CD spectroscopy—fight plane polarized in the yz-plane can be described in mathematical terms as being comprised of left or right circularly polarized components of equal phase and amplitude (b). The perspective is depicted schematically toward the source. (Reprinted from Mack, Stillman and Kobayashi, Elsevier 2007)...

The combination of collinear fast-beam laser spectroscopy and P-RADOP (radiation-detected optical pumping) has been used to measure nuclear spins and moments of neutron-rich isotopes of the light alkali elements jLi [72-74] and Na [75]. Here, the optically pumped fast atomic beam is implanted into a single crystal placed in a static magnetic field. The NMR signal is destroying the nuclear polarization detected by measuring the p-decay asymmetry. 

A typical experimental arrangement for level-crossing spectroscopy is depicted in Fig. 12. Atoms or molecules in a homogeneous magnetic field B = 0,0, B are excited by the polarized optical wave E = Ey cos(cot — kx) and tuned to the transi-... 

The principle of Mossbauer polarometry is similar to that of optical polarometry. In this case, the polarization and the analysis can be performed by appropriately oriented external magnetic fields. Using Fe polarization spectroscopy 36 lines, rather than six, are observed with... 

The triplet-sensitized photo-decomposition of azocumene into nitrogen and cumyl radicals was investigated by TR EPR and optical spectroscopy. " The cumyl radicals observed carry an initial spin polarization and are formed with a yield which depends on both the solvent viscosity and the strength of the external magnetic field. This phenomenon is interpreted in terms of a depopulation-type triplet mechanism, i.e. competition between decay into radicals and fast triplet sub-level intersystem crossing" back to the azocumene ground state.
