“…Transition due to 4 I 9/2 → 2 G 7/2 of [Nd(HFA-D) 3 ] in organic solvents was observed as a predominant band at 582 nm. Relatively intense absorption of 4 I 9/2 → 4 F 7/2 transition is a feature of the absorption spectrum of the complex in solution, which is not observed for LHG-8 glass and Nd:YAG. − 1 Transmittance spectrum (a) and emission spectrum (b) of 0.1 mol m -3 [Nd(HFA-D) 3 ] in DMSO- d 6 .…”
The deuterated tris(hexafluoroacetylacetonato)neodymium(III) complex, Nd(HFA-D) 3 , was obtained by ketoenol tautomerism reaction of Nd(HFA) 3 in methanol-d 4 . The emission of Nd(HFA-D) 3 was observed in the following anhydrous deuterated organic solvents: methanol-d 4 , acetone-d 6 , THF-d 8 , DMF-d 7 , and DMSO-d 6 .The intensity and lifetime of the emission in DMSO-d 6 are much superior to those in other deuterated solvents. The specific interaction of DMSO molecules with Nd(HFA) 3 was confirmed by 13 C NMR and 19 F NMR analysis. The strong coordination ability of DMSO to Nd 3+ ion in Nd(HFA-D) 3 led to the enhanced emission in DMSO owing to the suppression of radiationless transition via vibrational excitation of D 2 O molecules in the vicinity of Nd(HFA-D) 3 .
“…A primary beam of Cs + at 23 keV impact energy and with an ∼1-2 nA focussed beam was rastered over a 10 × 10 mm 2 area, and a normal-incidence electron gun was tuned to overlap the rastered area for optimal charge compensation. The mass spectrometer was tuned to resolve molecular ion interferences ( 16 OH and H 2 16 O on 18 O and 17 O, requiring MRP of ∼2000 and ∼6000, respectively). Either 16 O and 18 O (L2 ′ and H1 Faraday Cup FC detectors), or 16 O, 17 O, and 18 O (L2 ′ , FC2, and H1 FCs) were simultaneously detected with a 10 10 U resistor for measuring 16 O and 10 12 U resistors for the minor isotopes.…”

A static magnetic eld was maintained by NMR regulation, and integration times were adjusted to achieve <0.2& (2 standard error; SE) internal precision for the relevant isotopic ratios.…”
