Shortest bond length

The application of 170 NMR spectroscopy to obtain structural information about polyoxoanions, mainly in nonaqueous solution, had been examined and discussed in detail (99). A very useful finding was that chemical shifts are determined largely by metal-oxygen bond strengths. An inverse correlation exists between the 170 shift and the shortest bond length to a given metal. In aqueous solution the existence of [Mo7024]6 could be confirmed by the use of 170 and "Mo NMR spectroscopy (100-104). Evidence for the existence of the three... 

One can easily note that Eq. (4.138) is similar to the solution given by Eq. (4.126), which is derived from the assumption of a constant friction and complete neglect of the Poisson expansion. The solution for Zma, which is the shortest bond length required to maintain a stable debonding process, is obtained from Eq. (4.137)... 

In contrast to fluorosilanes with pentacoordinate silicon systems such as 235-237, it is very difficult to find similar compounds of chlorosilanes to establish the Si—Cl bond length in similar cases. X-ray crystal structure is available for only few of these compounds and only typical cases of the shortest and longest Si—Cl bonds are given. The shortest bond lengths are found in compounds where the silicon is bonded to a metal such as... 

Which of the following diatomic molecules has the shortest bond length ... 

Prepare a molecular orbital energy level diagram for nitric oxide (NO) and predict the bond order of this molecule. On the basis of the molecular orbital diagram, what do you predict for the bond orders of NO+ and NO Which of these diatomic species would you expect to have the shortest bond length Why ... 

Dong et al. [35] analyzed the multiple bimetallic bond of Cr-Cr, V-Mn, V-Tc, Nb-Mn, Cr-Mo, Mo-Mo, and Nb-Tc using CASPT2. They determined the bimetallic bond length, NBO, EBO, formal shortness ratio (FSR) values, and Mulliken charge populations for these systems. The V-Mn molecule presents the shortest bond length value and the largest FSR value in the series. 

The RuC molecule shows the largest bond energy and shortest bond length of any of the 4d transition metal carbides [OlDaB], There are three low-lying states A2, in that order) which were assigned successfully... 

The shortest bond length of 176 pm in the trichlorosilyl compound sitrol (Figs, lb and 6) might be energetically favored for steric reasons by the undulated perhydropyridine ring. 

The Qj p—H bond has the shortest bond length and is therefore the strongest bond. The C —H bond has the longest bond length and is therefore the weakest bond. Compare the spectra of an alkane, an alkene, and an alkyne (Figure 15.10). In each case, we draw a hne at 3000 cm ... 

C2 has the highest bond order, the highest bond energy, and the shortest bond length. 

Notice that the C9-C10 bond is a double bond in four of the five resonance structures. No other bond in phenanthrene has this feature. As such, the C9-C10 bond is expected to have the most double-bond character, and consequently, the shortest bond length.
