โœฆ Synopsis


The anisotropic resonance frequency shift ~v= v(HD) -v(ortho-He singles) of the I H resonance spectrum observed in low ortho-concentration (X <_ 0.01) solid He single crystal samples is examined The observed sign and magnitude of the resonance frequency shift as well as its anisotropy are explained by the spin-rotation interaction and the second order effects of the intra-molecular dipole-dipole interaction of ortho-H2 singles. The calculations, without adjustable parameters, are in reasonable agreement with the experiments. This conclusion is at variance with the suggestion by Delrieu and Sullivan.

We report measurements of the shifts of the ortho-H 2 NMR absorption lines relative to HD as a function of temperature (0.05 < T < 0.38 K) for an applied magnetic field of 6.3 T. At these fields the principal thermal polarization effect is the shift due to the i".] coupling between the nuclear spin

H NMR spectra of the spin-crossover compound [Fe(ptz) 6 ](BF 4 ) 2 and its zinc(II) analogue were recorded on polycrystalline samples as the function of decreasing temperature in order to study the connection of the change in the electronic state and the molecular motions present in both crystals. T
