Nitroxide paramagnet-induced para-ortho conversion and nuclear spin relaxation of H2 in organic solvents.
The kinetics of para-ortho conversion and nuclear spin relaxation of H 2 in chloroform- d 1 were investigated in the presence of nitroxides as paramagnetic catalysts. The back conversion from para-hydrogen ( p-H 2) to ortho-hydrogen ( o-H 2) was followed by NMR by recording the increase in the intensity of the signal of o-H 2 at regular intervals of time. The nitroxides proved to be hundreds of...
متن کاملNuclear relaxation of H2 and H2@C60 in organic solvents.
The 1H nuclear spin-lattice relaxation time (T1) of H2 and H2@C60 in organic solvents varies with solvent, and it varies proportionally for H2 and for H2@C60. Since intermolecular magnetic interactions are ruled out, the solvent must influence the modulating processes of the relaxation mechanisms of H2 both in the solvent cage and inside C60. The temperature dependence of T1 also is very simila...
متن کاملNUCLEAR MAGNETIC RESONANCE iN DILUTE ALLOYS
The experimental results concerning the electric field gradient and the local magnetic field around substitutional impurities in copper-based dilute alloys have been summarized. Comparing the experimental data with theoretical models we have come to the conclusion that only the first-order quadrupole wipe-out number characteristic of the asymptotic charge density oscillation around the impuriti...
