It is possible to study the very rapid exchange rates between molecules or ions, L, coordinated to paramagnetic ions and the jiee molecules or ions, L\*, in the body of the solution by measuring the line width of the N M R signal of L\*.
The kinetics of exchange of the whole molecule between salvation sphere of A13+ and bulk at A1(C104)3 in CH30D, CH3CD20D and CD3CH20D has been studied by means of line-shape analysis of.PMR spectra of methyl and methylene groups. The activation enthalpy A H 4 of 65 kJ/mol for methanol and 52 kJ/mol
## Abstract Four new ligands, namely the Nβsubstituted 2β(4βsulfonyl)βpyrrylmethyl derivatives of methylamine, glycine, ethylenediamine and iminodiacetic acid, were synthesized to investigate the coordinating tendency of pyrrolic nitrogen in aqueous solution. The complex formation of these ligands
