Spin-lattice Relaxation of Reorienting or Tunneling Deuterated Methyl Groups
نویسنده
چکیده
Tae spin-lattice relaxation of deuterated methyl groups, which is exponential at high temperatures, becomes non-exponential at low temperatures as evidence of the coupling between the Zeeman and tunneling systems. The dominant relaxation is considered to be the quadrupole interaction. Experimental results at liquid nitrogen and liquid helium temperatures support the theoretical model.

Proton Spin-lattice Relaxation in Amorphous States of Organic Molecular Solids
We have measured the temperature dependence of the proton spin-lattice relaxation rate R at 8.50 and 22.5 MHz in solid 1,3,5-tri-ethyl-benzene and solid 1,2,4-tri-ethyl-benzene. Analysis of the data strongly suggests that we are studying amorphous states in these slowly solidified organic solids (that are liquids at room temperature). The ethyl groups are static on the Larmor frequency timescal...
متن کاملMethyl rotational tunneling dynamics of p-xylene confined in a crystalline zeolite host.
The methyl rotational tunneling spectrum of p-xylene confined in nanoporous zeolite crystals has been measured by inelastic neutron scattering (INS) and proton nuclear magnetic resonance (NMR), and analyzed to extract the rotational potential energy surfaces characteristic of the methyl groups in the host-guest complex. The number and relative intensities of the tunneling peaks observed by INS ...

The molecular dynamics of tetramethylstibonium hexafluorophosphate, [Sb(CH3)4]PF6 , is investigated over a broad temperature range. NMR spin lattice relaxation times and the N M R second moments of the *H and F nuclei were determined in the range 8.6 < T/K ^ 332.3 for polycrystalline [Sb(CH 3) 4]PF 6 . The complex cation undergoes isotropic tumbling for T > 2 6 0 K and thermally activated methy...
متن کاملCommunication: Dissolution DNP reveals a long-lived deuterium spin state imbalance in methyl groups.
We report the generation and observation of long-lived spin states in deuterated methyl groups by dissolution DNP. These states are based on population imbalances between manifolds of spin states corresponding to irreducible representations of the C3v point group and feature strongly dampened quadrupolar relaxation. Their lifetime depends on the activation energies of methyl group rotation. Wit...
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...
