The concentration dependence of the fluoride ion spin-lattice relaxation rate has been observed by nuclear magnetic resonance experiments on samples of defatted and dried bone. The 19F spin-lattice relaxation rates increased linearly with the bone fl

The 19F NMR properties of fluoridated rat bone powder samples have been studied in several external magnetic fields. The results show a characteristic field dependence, related to the strength of chemical shift interactions compared to dipole-dipole

The motionally narrowed proton NMR absorption lineshape is calculated for the NH 4 + tetrahedron reorienting by ±180° jumps about all three of its C 2 axes. Conditions which must be met for the spectrum to be observed experimentally are discussed.

A semiclassical theory of proton magnetic-resonance absorption of the N${\mathrm{H}}_{4}^{+}$ ion in solids is presented. In this theory, the lattice variables are treated as classical functions of time, while the nuclear spins are treated quantum me

There are four basic types of spin polarization torsional spectroscopy (SPOTS) experiments, corresponding to four time domains of observations. It is possible to determine the spectrum, the specific heat, and the relaxation time of the set of energy

Observation of the visible fluorescence of the SiF radical in SiF4 gas irradiated by the pulsed output of a CO2 laser leads to the conclusion that the molecules are dissociated into electronically excited fragments by the action of the intense laser

The proton T 1 temperature dependence of CH 4 gas in a deuterated clathrate lattice deviates from the semiclassifical predictions. The discrepancy is partially accounted for by including the effects of symmetry and the quantization of rotational stat
