The phrase "postulated on the basis of" is correct and usable in written English.
It is typically used to describe a hypothesis that is founded on a specific set of facts or observations. For example, "His theory was postulated on the basis of evidence collected at the crime scene."
The protonic conductivity mechanism in the hydrogels studied is postulated on the basis of these investigations.
A possible mechanism for anion triphenylborane interactions is postulated on the basis of conductivity and FT-IR spectroscopy results.
Many aspects of protolanguages are postulated on the basis of a careful comparison of the features of the known descendant languages and so are derived rather than diagnostic in nature.
The possible reaction mechanisms/pathways for the formation of cross-linked networks from para-hydroxybenzylamine intermediates are postulated on the basis of these structural changes.
Greenwood and his colleagues postulated, on the basis of a number of other features in both modern and fossil fishes, that this similarity is overridden by more-fundamental differences that indicate a long history of phyletic separation.
Continuous flow catalytic activity of the nanostructured monolithic columns towards hydride-mediated reduction of nitrophenol isomers, namely 2-nitrophenol, 3-nitrophenol and 4-nitrophenol, and 4-nitroaniline was postulated on the basis of UV vis spectroscopy characterization suggesting presence of the corresponding amino-derivatives.
Traditionally, such forces are represented by disjoining pressures that are postulated solely on the basis of the local film thickness, disregarding the local slope and curvature of the interfacial profile.
The affinities presumed to act between chemical 'atoms' were postulated solely on the basis of the observed chemical behaviour of bulk substances manipulated in the laboratory.
At any instant in time, the ratio of their rates can be determined and episodes of synchronization can be postulated simply on the basis of coincident stability of the rates over defined periods of time.
A different and much larger conformational change has been postulated for TtNapA on the basis of its outward-open x-ray structure and an inward-open state modeled on the dissimilar EcNhaA structure (Lee et al., 2013a).
Multiple studies have postulated on the causes of trunnionosis.
