## Abstract The contributions to the ^13^C NMR spinโlattice relaxation rates of both protonated and nonโprotonated carbons of a range of carbocations in superacids were determined from the analysis of __T__~1~ values measured over a range of temperatures and at different field strengths. From the d
The paper is devoted to investigations of spin-lattice relaxation ation determined by nuclear dipole-dipole interactions for processes in 99% 13 C-enriched diamonds. Relaxation time measpin-1 2 nuclei and T imp 1 is the impurity component of the spinsurements were performed as a function of orientat
