Abstract
The possibility of determining the direct proton-carbon relaxation term, ρ{variant}CH, as the difference between the spin-lattice relaxation rate of proton nuclei and their satellite signals is investigated. Comparison of the ρ{variant}CH values obtained from carbon and proton relaxation measurements in a 0.5 mol dm-3 purine solution confirms the reliability of the proposed method. The existence in bio-organic molecules of proton nuclei with different relaxation pathways depending on the magnetic properties of the vicinal carbon is demonstrated. © 1987.
