“…In general, the experimental results for 23 Na and 28 Na are well described by the sd shell plus core-polarization calculations. The small quadrupole moments for 26 Na and 27 Na are also small in the calculations but their actual values are not so well reproduced.…”

“…This interaction constant of 28 Na in NaNO 3 can be ascribed to regular lattice sites for which also the quadrupole interaction of 23 Na is known 6 . This is not only expected from general experience but also supported by experimental arguments.…”

“…The calculation of the moments is based upon the wave functions obtained in the full sd model space 1d 5=2 , 1d 3=2 , 2s 1=2 with the USD Hamiltonian of Brown and Wildenthal 7 . These calculations with the sd-shell basis can account for the deformation near 23 Na, but the sd-shell wave functions for 31 Na and other nuclei with N = 20 such a s 32 Mg are spherical. To account for the deformation near N = 20 one has expand the basis to include the f p -shell intruder states.…”

The nuclear electric quadrupole moments of the isotopes 26 Na, 27 Na, 28 Na and 29 Na were measured by -NMR spectroscopy in single crystals of LiNbO 3 and NaNO 3 . High degrees of nuclear polarization were produced by optical pumping of the sodium atoms in a fast beam with a collinear laser beam. The polarized nuclei were implanted into the crystals and NMR signals were observed in the -decay asymmetries. Preparatory measurements also yielded improved values for the magnetic moments of 27,31 Na and con rmed the spin I = 3=2 for 31 Na. The results are discussed in comparison with large-basis shell-model calculations.

Investigation of structure and dynamics in the sodium metallocenes CpNa and CpNa·THF via solid-state NMR, X-ray diffraction and computational modelling

Solid-state (23) Na NMR spectra of two organometallic complexes, cyclopentadienylsodium (CpNa) and the tetrahydrofuran (THF) solvate of CpNa (CpNa·THF), are presented. Analytical simulations of experimental spectra and calculated (23) Na electric-field gradient (EFG) tensors confirm that both complexes are present in microcrystalline samples of CpNa recrystallized from THF. For the solvate, (23) Na NMR experiments at 9.4 T and 11.7 T elucidate sodium chemical shielding (CS) tensor parameters, and establish that the EFG and CS tensor frames are non-coincident. Single-crystal X-ray diffraction (XRD) experiments are used to determine the crystal structure of CpNa·THF: Cmca (a = 9.3242(15) Å, b = 20.611(3) Å, c = 9.8236(14) Å, α = β = γ = 90° , V = 1887.9(5)Å(3) , Z = 8). For CpNa, (23) Na NMR data acquired at multiple field strengths establish sodium CS tensor parameters more precisely than in previous reports. Variable-temperature (VT) powder XRD (pXRD) experiments determine the temperature dependence of the CpNa unit cell parameters. The combination of (23) Na quadrupolar NMR parameters, pXRD data and calculations of (23) Na EFG tensors is used to examine various models of dynamic motion in the solid state. It is proposed that the sodium atom in CpNa undergoes an anisotropic, temperature-dependent, low frequency motion within the ab crystallographic plane, in contrast with previous models.

Abstract. The hyperfine levels of the sodium 3P1/2,3/2 states were resolved using a narrow linewidth laser to excite the ground state. The laser frequency was scanned while fluorescence resulting from the radiative decay of the excited state was detected. The frequency was calibrated using the known hyperfine splitting of the ground state. The magnetic dipole A and electric quadrupole B hyperfine coupling constants of the excited states were determined to be A3e, 2=94.44+0.13, A3p~2=18.62+ 0.21 and B3e~/ =2.11~0.52MHz. The uncertainty o-fA3e,/z is less than results previously reported while the data for the 3 P3/a state are consistent with those existing in the literature.
