We have determined the molecular and crystal structure of 4,5-dibromo-2,7-di-t-butyl-9,9-dimethylxanthene and measured the (1)H spin-lattice relaxation rate from 87 to 270K at NMR frequencies of omega/2pi=8.50, 22.5, and 53.0MHz. All molecules in the crystal see the same intra and intermolecular environment and the repeating unit is half a molecule. We have(More)
