Original Paper


We have computed the Gaussian G4 structures, enthalpies of formation, and Gibbs free energies of formation of four trans-1,2-dialkylcyclopentanes. Aside from their intrinsic interest as products of petroleum refining, we wish to use these simple trans-1,2-dialkylcyclopentanes as a database in the study of larger, more complicated molecules like prostanoic acid and its derivatives, the prostaglandins.
