The NMR lineshape for a distribution of correlation times has been calculated by a random walk model using the local frequency approximation for isotopic reorientation and 3cos 2θ1 angular dependence. It has been found that the sharp cutoff approximation used earlier is well justified for a width...
Observation of a Doublet in the Quasielastic Central Peak of Quantum-Paraelectric SrTiO3 喜欢 0 阅读量: 15 作者:B Hehlen,AL Pérou,E Courtens,R Vacher 摘要: Rayleigh-Brillouin light-scattering spectroscopy performed on oriented samples of tetragonal SrTiO3 reveals the presence of a new doublet...
Here, we report a mechanistic analysis of the conformational dynamics of two Ig domains from the N terminus of titin, Z1Z2, by using X-ray crystallography, SAXS, NMR relaxation data, and residual dipolar couplings in combination. Z1Z2 preferentially adopts semiextended conformations in solution...

We report results of 27Al-NMR measurements on a single crystal of PrTi2Al20, in which the ground state of Pr3+ ions in the crystalline electric field is the nonmagneitc Γ3 doublet. From the analysis of NMR spectra with the magnetic field applied precisely along the 111 and 100 direction...
摘要: The ground state of sup 95 Zr is studied using (d,p) reaction on sup 94 Zr by 15.5 MeV deuterons. With a resolution in energy of about 13 KeV it was shown that this g.s. is in fact a doublet with a separation of about 23 KeV. (Atomindex citation 17:034640)关键词:...
