Deuteron and Niobium‐93 Magnetic Resonance Study of Niobium Deuterides

Abstract: Ker.i~yutrt~ri~ppo~resonanz Mngnetische Kernresonnnz / Phnsenunn.vandlungen 1 Stoffeigenscliuflen Niobium deuterides in the composition range NbD,,,, -NbD,,,, were investigated by means of deuteron and 93Nb magnetic resonance over the temperature range 4.2-420 K. The 0-a transition, in the temperature range 340-415 K for these compounds, is sharply defined by the extinction of the deuteron quadrupole interaction as well as by the appearance of the central component of the 93Nb spectrum when the cubic a phase i… Show more

“…However, its moderately sized nuclear quadrupole moment ( Q ( 93 Nb) = −0.32 × 10 -28 m 2 ) often results in severe quadrupolar broadening of central-transition NMR powder patterns, which in some cases is prohibitive in terms of routine spectral acquisition and interpretation. Nonetheless, solid-state 93 Nb NMR has been used to study a variety of different systems, including inorganic niobium halides, intercalated H-bronzes of NbVO 5 , niobium borides and deuterides, , and a variety of niobates. There have also been a number of 93 Nb NMR studies featuring a variety of modern two-dimensional (2D) solid-state NMR experiments, including multiple quantum magic-angle spinning (MQMAS) and satellite-transition magic-angle spinning (STMAS) experiments, which are used for resolving peaks that may be obscured due to broad overlapping quadrupolar NMR patterns, as well as nutation and 2D-exchange NMR. …”
