WebCuH bonds in the two weakly interacting species. The bond additivity procedure is shown to perform well in the present case, and bond polarizabilities of 4.256 and 3.964 a.u. are proposed for the CuH and the CuC bond, respectively.

WebIn this chapter, we will use bond stiffness fe= 100. The exact position of a signal indicates subtle factors that affect bond stiffness, such as resonance. Using nominal nuclear masses gives k values of 958, 512,408, 311 Nm , respectively. Decreasing bond stiffness implies decreasing bond strengths. (Observed Do values are, in kJmol 564, 428 ...
