WebSummary: Over the quarter century since the publication of Flory's classic Statistical Mechanics of Chain Molecules, the rotational isomeric state model for averaging conformation-dependent properties of macromolecules has become a popular tool of polymer chemists, and it has been improved and refined in numerous important ways. … WebApr 12, 2024 · Conformational Isomers. The C–C single bonds in ethane, propane, and other alkanes are formed by the overlap of an sp 3 hybrid orbital on one carbon atom with an sp 3 hybrid orbital on another carbon atom, forming a σ bond (Figure 23.2.1).Each sp 3 hybrid orbital is cylindrically symmetrical (all cross-sections are circles), resulting in a …
