“…A larger ring structure introduces more organization into the molecule than a smaller ring structure, and this leads to different impacts on the entropy and heat capacities. The disability of the group additivity theory to describe intramolecular interactions was similarly found to be the main source of errors during the development of a kinetic group additivity scheme for the reaction rate coefficients of the unimolecular decomposition of cyclic ethers . From the distribution of the differences, no systematic deviations can be observed for any of the thermodynamic properties.…”
