Exchange Rates of Ligands in Complex Ions

Abstract: Lifetimes of' coordinated ligands that can be nieasirred fall into the range of milliseconds to microseconds. The lifetime, or an upper limit to the lgetime, can be measured directly,

“…In a discussion of the theoretical equations for the transverse relaxation rate, \/T 2M , where M refers to the complex, Pearson and Anderson [112] pointed out that there were two mechanisms, a dipole-dipole interaction and an isotropic contact interaction. The actual presence of an electron on the proton and the consequent coupling of the electron and nuclear spins is necessary for the latter interaction, which also necessitates contact between the molecule containing the proton being studied and the paramagnetic ion.…”

“…The technique described in Section 3.2 was applied to the reaction in Figure 3.1 as follows (essentially as presented in Pearson et al 41 ): It should be noted that the reaction depicted in Figure 3.1 is not actually the reaction of interest, as we are concerned with the rate of coordination of a free metal ion by free ligand. However, measuring the rate of the reaction in Figure 3.1 is sufficient for two reasons.…”

“…A few other factors, such as the electron spin relaxation time , the dipolar correlation time of the tumbling hydrated complex, , and the frequency of the applied rf field, are also important. Following the presentation in Pearson, [40][41][42] let us begin again with the Bloch Equations including chemical exchange for 1/T2:…”
