Vibrational stretch frequency

Table 2.10 Vibrational Stretching Frequencies and Force Constants...

There are two aspects of the structural chemistry of cyano complexes that we shall discuss here the coordination of the metal atom, and relative values of interatomic distances and vibrational stretching frequencies.1 The correlation between the distances and frequencies and the very limited available thermodynamic data is considered briefly at the end of the section. 

Type III. EPR-silent binuclear copper site that binds dioxygen as peroxide and exhibits unusual physicochemical characteristics (1) diamagnetism, (2) two characteristic absorption bands at 350 and 580 nm, and (3) a low O—O vibration stretching frequency (-750 cm-1). 

S4 symmetry of which two planar T-shape Pt(CO)3 fragments are associated in perpendicular configuration through the Pt-Pt bond is obtained by the dissolution of Pt02 in concentrated sulfuric acid (Scheme 13). The vibrational stretching frequencies of carbonyl are over 2200 cm , and the C MAS NMR measurements are found below 5140. 

C) in electrochemistry, and Vco versus electrode potential relationships for CO on Pt hlack. Third, variations in vco can be directly correlated with changes in 27t back-donation the higher the back-donation, the lower the CO stretch frequency. When taken together, all these observations suggest that the electrode potential dependence of both the C NMR shift and the vibrational stretch frequency of adsorbed CO are primarily electronic in nature, and originate from changes in the rLDOS at the metal surface and at the adsorbate, induced by electrode polarization.

Isotope Effects. - Gawlita et researched the variation of the C-D vibrational stretching frequency in primary and secondary alcohols. They affirm that the bond order of C-D in the 2-propanol-methoxide complex decreases by 7.5%, erroneously assuming that determines this quantity.
