Abstract
This spin-lattice relaxation times T1 of protons in the presence of the shift reagent Eu(FOD)3-D27 and the relaxation reagent Gd(FOD)3 were employed for the structure analysis of 1-adamantanol, 4-diamantanol, adamantanone, and 2,2-dioxy-2-thiaadamantane. The structure models of the complex adducts of the substrates with Gd(FOD)3 are discussed. The dependence of the corrected spin-lattice relaxation rates on the relaxation reagent concentration is linear only in the region of low concentration.
