Coals of NCB rank 301 a (coking), 502 (caking) and 802 (very weakly caking) are oxidized in air at 373 K or 383 K for up to 42 days. Spin-lattice and spin-spin relaxation times, 7, and T2 respectively, of oxidized coals are measured using a Bruker SXP 4-l 00 and FT spectrometer. Free radical concent

Carbon-13 and proton spin-lattice relaxation times have been discussed in terms of intramolecular motions for solutions of poly(dimethyl-and poly(diphenylphenylene.oxides). The most suitable auto-correlation function seems to be a sum of several exponential modes. Comparison with the results of prev

When red blood cells are deoxygenated, hemoglobin, which is then transformed into deoxyhemoglobin or methemoglobin, becomes paramagnetic. The transverse nuclear magnetic relaxation rate of water protons is considerably enhanced by this chemical transformation. A general agreement exists about the or

## Abstract Spin‐lattice relaxation rates of water protons in hydrated immobilized lysozyme are measured as a function of magnetic field strength. The dependence of water relaxation versus hydration is presented from 35 to 55% by weight water content. The water‐proton relaxation is directly coupled
