متن کامل14N Nuclear Quadrupole Coupling — Correlation of Experimental and Theoretical Values with Structure*
In our first two papers on 14N nuclear quadrupole coupling constants (NQCC, Xij) [U 2], we showed that double zeta (DZ) ab initio molecular orbital calculations using a Huzinaga/Dunning 9s5p/4s basis [3] gave good linear correlations between the experimental microwave (MW) NQCC and the cal culated electric field gradients (EFG, <?,,) for a range of heterocyclic and other organic molecules. Fun...
متن کاملDiffusion in Intermetallic Compounds Studied Using Nuclear Quadrupole Relaxation
The jump frequency of Cd tracer atoms was measured as a function of temperature in seven rare-earth tri-indide intermetallic compounds having the L12, or Cu3Au, structure. The frequency, proportional to the diffusivity, was detected by relaxation of nuclear quadrupole interaction at Cd nuclei caused by reorientation of the electric field gradient in each diffusive jump. Measurements were made u...
متن کاملAtom movement in In3La studied via nuclear quadrupole relaxation.
Jump frequencies of Cd tracer atoms in In3La were measured via nuclear quadrupole relaxation caused by stochastic reorientation of the electric field gradient using the method of perturbed angular correlation of gamma rays. Activation enthalpies of 0.53(1) and 0.81(1) eV were found at the two phase boundaries, which differ in composition by only about 0.1 at. %. The jump frequency was found to ...
