, p. 7676 - 7686 (1990)
Dye laser excitation and fluorescence spectra have been used to provide information on rotational structure and energy linkages between several low-lying electronic states of YbO.Configurational assignments of the observed low-lying states have been made
Temperature dependent rate constants for the reactions of gas phase lanthanides with N2O

The reactivity of gas phase lanthanide (Ln) atoms (Ln=La-Yb with the exception of Pm) with N2O from 298 to 623 K is reported. Lanthanide atoms were produced by the photodissociation of Ln(TMHD)3 (TMHD=2,2,6,6-tetramethyl-3,5-heptanat

Diytterbium monoxide monocarbide (fcc, a = 4.857 ± 0.002 ?), prepared by reaction of stoichiometric mixtures of sesquioxide, metal, and graphite in sealed tantalum ampoules, was found to vaporize according to the reaction 6Yb2OC(s) → 2Yb2O3(s) + 3YbC2(s) + 5Yb(g) The equilibrium vapor pressure has been measured by a target collection Knudsen effusion technique in the temperature range 1120-1397°K. For the vaporization reaction ΔH°1259 = 264.5 ± 3.6 kcal/gfw and ΔS°1259 = 104.7 ± 2.9 eu. The heat capacity of the oxide carbide has been estimated, and second- and third-law results are presented. For Yb2OC(s) ΔHf°298 = -169.0 ± 4.5 kcal/gfw, ΔGf°298 = 163.3 ± 4.5 kcal/gfw, and S°298 = 34.9 ± 4.6 eu. Experimental results and thermodynamic calculations indicate that diytterbium monoxide monocarbide is the phase previously reported to be ytterbium monoxide.
