This means that the behavior of multiple bonds in parallel cannot be simply extrapolated from single bond measurements.
From theCambridge English Corpus

Here we will discuss two different scenarios : namely, multiple bonds in series and multiple bonds in parallel.
From theCambridge English Corpus
In the processes of forming complex organic molecules, reactive species possessing unsaturated multiple bonds play an important role.
From theCambridge English Corpus
Because adhesion between extended surfaces is determined by the dynamic equilibrium of multiple bonds, surface detachment is not determined by a single kinetic event - that is, single bond dissociation.
From theCambridge English Corpus
In the examples discussed above, the adhesion energy reflects the energy change upon the formation of the multiple bonds that contribute to the strong, short-range binding interactions.
From theCambridge English Corpus
The engagement of multiple bonds ensures strong overall adhesion, or stable binding, while allowing for plasticity at adhesive junctions, the formation of dynamic contacts, and cell motility.
From theCambridge English Corpus
The quantitative measurement and analysis of multiple bonds in biological systems, including bonds in series and bonds in parallel, remains an important but unsolved problem for both experimentalists and theoreticians.
From theCambridge English Corpus
At higher densities where adhesion can involve multiple bonds, the rupture forces are estimated from the average bond strength or by comparing the adhesive behavior with simulations.
