Ligand bond strength

Photoelectron spectra of cluster ions yields cluster-bond strengdis, because each added ligand increases the bindmg energy of the extra electron in the negative ion by the amount of the ligand bond strength (provided the bond is electrostatic and does not appreciably affect the cln-omophore ion) [116].

In the chemistry of main-group element sulfoxide complexes, a relationship between Aj/(S=0) and the enthalpy of formation of the sulfoxide complex has been derived (159). The applicability of the equation has only been examined for O-l SO complexes, and the constraints on using Ai (S=0) as a measure of metal-ligand bond strength should be borne in mind during its application.

The pH dependence of could be due to changes in A-B loop disorder rates, perhaps the chemical exchange phenomenon observed for NPl-ImH (Section ll,E,2,b), or to changes in ligand bond strength. The change in lies in the off-rates (Tables I-Ill) consistent with the loop disorder model. Plots of vs pH display an excellent fit with the equation for a titration curve (Fig. 21), indicating that the transition... 

Vibrational frequencies measured in IR experiments can be used as a probe of the metal—ligand bond strength and hence for the variation of the electronic structure due to metal—radical interactions. Theoretical estimations of the frequencies are obtained from the molecular Hessian, which can be straightforwardly calculated after a successful geometry optimization. Pure density functionals usually give accurate vibrational frequencies due to an error cancellation resulting from the neglect of... 

A third limitation arises because metal-ligand bond strengths in compounds formed by the transition metal elements located toward the bottom of the periodic table are generally greater than the bond strengths of the corresponding species that contain elements found... 

Metal ligand bond strengths via analysis of vibrational frequencies. 

The rate of reaction correlates with the metal-ligand bond strength of the leaving group, in a hnear free energy relationship (LFER, explained in the next section).
