Sign inversion in the MCD spectrum of the europium(3+) ion in aqueous solution

Sign inversion in the MCD spectrum of the europium(3+) ion in aqueous solution. Goerller-Walrand, C.; Godemont, J. (Lab. Anal. Anorg. Scheikd., Univ. Leuven, Heverlee, Belg.). J. Chem. Phys., 66(1), 48-50 (English) 1977. CODEN: JCPSA6. DOCUMENT TYPE: Journal CA Section: 73 (Spectra by Absorption, Emission, Reflection, or Magnetic Resonance, and Other Optical Properties) The magnetic CD spectrum of the Eu3+ ion in aq. soln. exhibits A terms for the transitions 5D1 .rarw. 7F0, 5D2 .rarw. 7F0, 5D0 .rarw. 7F1. The transition 5D2 .sigma.ar 7F0, which is a forced elec.In this experiment, several chemicals are used like 22541-18-0 and 13759-92-7 dipole 1, shows a sign inversion with respect to the 2 others, which are magnetic dipole allowed. By considering the expression for an A term in the light of the mechanisms which explain the intensity of rare earth spectra, only a trigonal sym. can account for this sign inversion. .

Physical Review B: Condensed Matter and Materials Physics, 74(19), 195101/1-195101/7 (English) 2006 American Physical Society. CODEN: PRBMDO. ISSN: 1098-0121. DOCUMENT TYPE: Journal CA Section: 77 (Magnetic Phenomena) We present characterization of the hyperfine interaction for the europium in hydrated europium chloride and as a dopant in yttrium orthosilicate. 12027-88-2 and 13759-92-7 are also in the experiment. The Zeeman and pseudoquadrupole tensors were detd. by measuring the hyperfine splittings while rotating the direction of a weak (~300 G) magnetic field. The hyperfine spectra were recorded using Raman-heterodyne spectroscopy, an radio-frequency optical double resonance technique. For both materials magnetic field values were identified where there is no first order Zeeman shift in a europium hyperfine transition. These field insensitive transitions will have application in achieving very long hyperfine coherence times. .
