Rapid 1H[13C]-resolved diffusion and spin-relaxation measurements by NMR spectroscopy.
Hadamard-encoded heteronuclear-resolved NMR diffusion and relaxation measurements allow overlapping signal decays to be resolved with substantially shorter measuring times than are generally associated with 2D heteronuclear cross-correlation experiments. Overall measuring time requirements can be reduced by approximately an order of magnitude, compared to typical 2D heteronuclear single-quantum...
متن کامل13C NMR Spin-Lattice Relaxation and Conformational Dynamics in a 1,4-Polybutadiene Melt
We have performed molecular dynamics (MD) simulations of a melt of 1,4-polybutadiene (PBD, 1622 Da) over the temperature range 400-273 K. 13C NMR spin-lattice relaxation times (T1) and nuclear Overhauser enhancement (NOE) values have been measured from 357 to 272 K for 12 different resonances. The T1 and NOE values obtained from simulation C-H vector P2(t) orientational autocorrelation function...
متن کاملSpin-Lattice Relaxation Below IK
NMR experiments at very low temperatures have been carried out for a long time, generally not as a general purpose method for analyzing structure and dynamics but rather as a convenient diagnostic tool in the study of substances whose special properties at very low temperatures are of interest. These include most prominently solid hydrogen and solid and liquid helium-3. It must always have been...
متن کاملProton and Fluorine Spin - Lattice Relaxation in
The spin-lattice relaxation times F, ('H) and 7, (l9F) in CoSiF6 • 6H-.0 have been measured at 30 MHz in the tem perature range 150K^F^400 K Both F,('H) and r, (l9F) decrease sharply at the phase transition tempera ture of 246 K (cooling cycle). The main relaxation mecha nism is assumed to be an Orbach process. From the 7", data an average splitting of the Co2+ ground state of about 400 cm"1...
متن کاملAnisotropic Spin -Lattice Relaxation of Deuterated Hexamethylbenzene
The anisotropic spin-lattice relaxation of deuterated hexamethy lbenzene (HMB-d,,) was measured at -36 and 70°C. The anisotropy is due to the anisotropic sixfold reorientation of the molecule about its hexad axis, and a model is presented to explain quantitatively the anisotropy, considering only single-particle relaxation. The temperature dependence of T, was measured, and the activation energ...
