There is doubtful statistical significance in the trend observed in the bondlengths. However, it appears that the similarity in the data for the samples is indicative of similar local structure at all stages of polymer deposition. These values correlate very well with the known coordination number of six and a Ru-N distance of 2.056 A. Q4)...

For reproducing as closely as possible diabatic conditions, we have fixed the Cl—Cl bondlength at its neutral equilibrium value. This way, the system depends on two parameters as shown in Figure 1. Previous experimental and theoretical studies on similar systems, [1,18] have shown that electron jump from Li to the acceptor molecule CI2, which has, once relaxed, a positive vertical electron affinity (see Table 1), is likely to take place at a distance d, (see the definition of this parameter in Figure 1) which is superior to the LiCl equilibrium distance (MP2 value 2.0425 A). The description of this phenomenon in terms of MO and states will be briefly recalled in the next section. 

In early structural studies of adsorbates on surfaces there was an implicit assumption that the surface provided a rigid chequer board of identical sites into which atoms or molecules were adsorbed, the only structural parameters of interest being the lateral registry and the adsorbate-substrate chemisorption bondlength. It was, of course, understood that the surface could modify the adsorbate species, most obviously through partial dissociation, but also in more subtle ways, because this is the whole...

One structural parameter of potential interest in the adsorption of simple diatomic molecules, such as CO, NO and N2, is the intramolecular bondlength. Much of the motivation for studying such adsorbates is related to the way adsorption modifies the chemistry of these species as the basis for heterogeneous catalysis. Many such reactions involve scission of the intramolecular bond, and if the adsorption is of the... 

The basic finding was that for chemisorption bonds, as for those in inorganic materials generally, bondlengths, D, and bond order, n, appear to be related by a Pauling-like expression [141] between an adsorbate X and the metal surface atoms M of the type...
