Optically Detected Spin Locking of Zero Field Electronic Triplet States and Cross Relaxation in the Rotating Frame
The spin locking method known from NMR is shown to be useful also in ESR for investigating spin lattice relaxation problems and "slow" motions, e. g. questions of energy transfer by triplet states in organic molecular crystals, and probing of nuclear quadrupolar splittings even smaller than the ESR line width at zero magnetic field. Optically detected ESR spin locking experiments for isolated t...
متن کاملEfficiency of paramagnetic relaxation enhancement in off-resonance rotating frame.
Transferring from laboratory frame to off-resonance rotating frame for the (1)H spin can compensate the relaxivity loss for paramagnetic agents at the magnetic field strength higher than 3 Tesla and enhance water relaxation rate constant significantly. A comprehensive theory for calculating the relaxation rate constants in the off-resonance rotating frame is described. This theory considers the...
متن کاملDependence of rotating frame relaxation rates on frequency offset: spin-lock versus adiabatic rotation
Introduction Rotating frame relaxation rates (R1ρ and R2ρ) measured during continuous-wave spin-lock pulse depend on the frequency offset (ΔΩ) between the pulse and the isochromat of interest [1]. This characteristic impairs a time-efficient utilization of this method for MRS applications in vivo, since data need to be acquired separately for each metabolite of interest. The present work invest...
متن کاملiDQC MR Imaging with Contrast of Off-resonance Rotating-frame Spin-Lattice Relaxation
Methods In Fig. 1, the low-power rf pulse (ω1)y and frequency offset ∆ω constitute an effective spin-locking field along the z′ axis of a tilted rotating frame, with an effective frequency 2 2 1 ( ) e ω ω ω = + ∆ and a tilt angle θ = arctan(ω1/∆ω) with respect to the normal Larmor rotating frame (θ = π/2 for an on-resonance spin-locking pulse without frequency offset) [1,2]. The magnetization a...
متن کاملNeutrino flux in the rotating reference frame
It is considered neutrino flux in the rotating reference frame. Due to the rotation of the frame, neutrino is observed as a superposition of two states P-transformed one from another. Since P-transformation is forbidden for neutrino, in the rotating reference frame one can detect a half of neutrino flux. Due to the rotation of the earth, the detector of neutrinos can measure a half of the solar...
