The temperature dependence of the spin lattice relaxation rates is discussed using a simple model. The similarities and the differences between proton NMR and deuteron NMR are pointed out. The main difference is that EaEb transitions are forbidden by spin selection rules in case of CH 3 , but ...
relaxation rate remains an universal function of the temperature, which is scaled by the Kondo resonance width, up to temperatures of the order of one hundred of this width; for temperatures lower then the Kondo temperature, the spin-lattice relaxation rate is proportional to the magnetic ...
The electron spin–lattice relaxation rate by the direct process for Ni2+ in lanthanum magnesium nitrate is surprisingly fast (5 × 103 s1 at 1.55 °K). Ni2+ is a non-Kramers ion, however, and consequently is strongly coupled to the lattice in most cases. The effective spin triplet and...

The spin-lattice relaxation of a Kramer's doublet arising from as-like ground state in any crystal symmetry is discussed. It is shown that in the cubic case the relaxation rate for one-phonon processes can be expressed in terms of the staticg value and its rate of change under dilatation...
The spin-lattice relaxation (SLR) of photoexcited triplet states in fullerene C60 crystal is investigated at low temperatures and high magnetic fields. The mixing of translatjional motions of the molecule and vibrational motions of the nuclei (TVM Relaxation mechanism) is chosen as the majo ...
1. Extrapolation to zero microwave power yields the inherent spin-lattice relaxation rate. The values of the relaxation rates (1/T1) as a function of temperature T measured between 1.4 and 4.2 K, forQA−Fe2+ and QB−Fe2+ are shown in Fig. 5 a, for QA−Zn2+ and for QB−Zn2...
The75As (I = 3/2) spin lattice relaxation rate divided by temperature,\((T_1T)_\mu ^{ - 1}\), for different field orientationsμ = z,yis shown in Fig.2both as a function of strainεand temperatureT. It is striking that while\((T_1T)_{\mathrm{z}}^{ - 1}\)incre...
