Cyclopentadienides of ytterbium (III) and ytterbium (II)

Journal of Inorganic and Nuclear Chemistry, 1966
Abstract The reaction of anhydrous ytterbium (III) chloride with sodium cyclopentadienide followed by crystallization from tetrahydrofuran (THF) gives the tetrahydrofuranate Yb(C5H5)3 · C4H8O (I), which can easily be converted into the ammoniate Yb(C5H5)3 · NH3 (II) by treatment with the stoichiometric amount of ammonia.

Magnetoresistance of Ytterbium

Physics Letters A, 1968
Abstract The magnetoresistance of Yb at 1.3°K and in magnetic fields up to 20 kOe is reported. The Fermi surface of Yb supports no open orbits and the single-OPW model of Yb is not adequate. It is suggested that the Fermi surface is closed and occupies a small volume.

Rotational Damping in Ytterbium Nuclei

Physical Review Letters, 2002
We have made the first clear measurements of rotational damping widths in nuclei. In a mixture of three Yb nuclei, these widths are 300 +/- 60 keV between 1.2 and 1.5 MeV gamma-ray energy [approximately (37-57)Planck's constant]. Compound damping and motional narrowing are discussed in connection with these results.

The vaporization behavior of ytterbium(III) fluoride and ytterbium(II) fluoride

Journal of the Less Common Metals, 1976
Abstract The modes of vaporization of stoichiometric YbF 2 and YbF 3 and of phases, or mixtures of phases, of intermediate compositions were studied at 1273–1833 K in high vacua using a molybdenum Knudsen cell. X-ray powder patterns, and the results of chemical analyses of vaporization residues, showed that YbF 2 and YbF 3 both vaporize ...

Static Dipole Polarizability of Ytterbium

The Journal of Physical Chemistry A, 2007
The static dipole polarizability of the ground state ytterbium atom is calculated using full and approximate relativistic ab initio methods. Our recommended polarizability of 143 au is consistent with experimental atomic spectral data. The corresponding van der Waals coefficient C6 of Yb2, derived using Padé approximants, is 2062 (200) au.

Reversible Mutarotation in a Macrocyclic Ytterbium Complex

Chemistry – A European Journal, 2010
AbstractM40 is a four‐fold symmetry macrocyclic ligand endowed with axial and central chiral elements, all of R configuration. It promptly binds late lanthanides (YbIII and LuIII) yielding a negative helicity, as witnessed by NIR‐electronic circular dichroism.

The calcium-ytterbium system

Journal of the Less Common Metals, 1968
Abstract Specimens of calcium, ytterbium, and seven calcium-ytterbium alloys have been examined over the temperature range 900 °–400 °C by differential thermal analysis. The results indicate the existence of a minimum in the melting point near 75 at. % ytterbium.
