Heavy-Ion Radiolysis of Cyclooctane
The Journal of Physical Chemistry, 1995The radiolysis of neat and iodine solutions of cyclopentane has been performed with 1-15 MeV protons, 5-20 MeV helium ions, 12-31 MeV carbon ions, and 22-32 MeV oxygen ions. The yields of the major products cyclopentene, bicyclopentyl, 1-pentene, and cyclopentyl iodide as well as the yields of a few select minor products have been determined.

The vibrational spectra and structure of cyclooctane
Spectrochimica Acta, 1959The Raman and infrared spectra of cyclooctane have been obtained under several conditions of temperature and state of aggregation. The infrared spectra of gaseous, liquid and solid cyclooctane contain essentially the same bands. No unequal dependence of band intensities on temperature is observed in either the Raman or infrared spectrum of the ...

Ab initio conformational analysis of cyclooctane molecule
Journal of Computational Chemistry, 1998The potential energy surface (PES) for the cyclooctane molecule was comprehensively investigated at the Hartree–Fock (HF) level of theory employing the 3–21G, 6–31G, and 6–31G* basis sets. Six distinct true minimum energy structures (named B, BB, BC, CROWN, TBC, and TCC1), characterized through harmonic frequency analysis, were located on the ...

Enantioselective Route from Carbohydrates to Cyclooctane Polyols
Organic Letters, 2005[reaction: see text] A synthetic route to select cyclooctane-1,2,3-triols and 1,2,3,4,5-pentaols has been defined. The starting materials are d-glucose or d-arabinose, and the key steps consist of a zirconocene-promoted ring contraction, a [3,3] sigmatropic rearrangement, and more extended functionalization of the resulting cyclooctadienone.

The excess enthalpies of cyclooctane + n-alkanes
Thermochimica Acta, 1982Abstract The excess enthalpies of cyclooctane + n -hexane, + n -heptane, + n -octane, + n -dodecane and + n -hexadecane have been measured over the whole composition range at two temperatures. The results, together with previously published excess volume results, have been fitted to the Flory theory of liquid mixtures.

Self-diffusion in crystalline hexamethylethane and cyclooctane
Journal of Physics and Chemistry of Solids, 1972Abstract Self-diffusion in the rotationally disordered crystalline phases of hexamethylethane and cyclooctane has been studied by high-resolution NMR linewidth measurements. The measured activation enthalpy for self-diffusion in hexamethylethane is 20·6 kcal/mole, or about twice the triple point sublimation enthalpy (9·33 kcal/mole), and it agrees ...
