Özet
The C-13 dipole-dipole relaxation times of the mixture of anti and syn isomers of free and complexed with Na+ and K+ dicyclohexano -18-Crown-6 were measured at 15 MHz The equilibrium constants, K(e) of each C-13 segment acting as a ligand site, were determined in methanol-d solution by the 1/K(e) [L0]n+m-1 = (1-np')n(1-mp')m/p' relationship where p' = p10/[1+p10(m-1)] which is the function of mole fraction of the complexed ligand p10 of expected stoichiometry.
