The errors commonly made when drawing cyclohexanes have been mentioned already, so I just want to summarize them briefly here.

Spectrochimica Acta Part A: Molecular Spectroscopy, 1973
Abstract A vibrational analysis has been carried out on cyclohexane, cyclohexane-d12, cyclohexane-1, 1,4,4-d4 and cyclohexane-1,1,2,2,4,4,5,6-d8 utilizing the set of 60 internal coordinates (all 18 bond stretches, all 36 valence angle bends and six CCCC torsional bends) that is compatible with the Snyder and Schachtschneider transferable valence ...

Chemical Engineering Science, 2011
Abstract In this communication, we first report hydrate dissociation conditions for the nitrogen+cyclopentane, cyclohexane or methyl cyclohexane+water and ethane+cyclopentane, cyclohexane or methyl cyclohexane+water systems at various temperatures. The experimental data were generated using an isochoric pressure-search method.

Radiation Protection in Cyclohexane
Radiation Research, 1958Protection of a substance against certain modes of radiolysis by introduction of a low-concentration solute which can interfere with the normal fate of some primary intermediate can be achieved by a variety of mechanisms (1). The system most extensively studied in this connection is cyclohexane + benzene. Reduction of the yield of hydrogen and ethylene

The infrared and Raman spectra of cyclohexane and cyclohexane-d12
Spectrochimica Acta, 1964Abstract This paper, reports the infrared spectrum of cyclohexane (100–3400 cm−1) and of cyclohexane-d12 (300–3400 cm−1), and the Raman spectrum with polarizations for both compounds. With these data the vibrational assignments have been advanced considerably.

Radiolysis of Cyclohexane. I. Pure Liquid Cyclohexane and Cyclohexane-Benzene Solutions
The Journal of Chemical Physics, 1960The radiation chemistry of pure liquid cyclohexane and of cyclohexane-benzene solutions has been investigated. The cyclohexane radiolysis system appears to contain at least two distinct activated species, one of which (c-C6H12″) is subject to ``protection'' by benzene while the other (c-C6H12′) is not.

VAPOR-PHASE RADIOLYSIS OF CYCLOHEXANE AND MIXTURES OF BENZENE AND CYCLOHEXANE
Canadian Journal of Chemistry, 1964The vapor-phase radiolysis of cyclohexane and benzene-cyclohexane mixtures has been studied with isotopic tracer techniques using C6D12 and C6D6. Benzene does not quench the molecular detachment of hydrogen, [Formula: see text] but interacts with the second-order processes giving HD in C6D12–C6H12 mixtures.

The structure of cyclohexane, F-, Cl-, Br- and I-cyclohexane
Journal of Molecular Structure, 1995Abstract The ground state, r0, and the average, r∗ , structures of cyclohexane were determined from the recently reported rotational constants for several isotopic species of cyclohexane. These structures provide a better description of the heavy atom skeleton in cyclohexane than the rs structure and allow an accurate prediction of the ...

Conformational analysis of cyclohexanes diastereoisomerism in disubstituted cyclohexanes
Resonance, 2005The cycloalkanes most commonly found in nature, viz., in some alkaloids, steroids and terpenoids contain six membered rings because they can exist in a completely strain free chair conformation. The fundamental understanding of the conformations of cyclohexane and the structures of molecules containing cyclohexane ring was developed by Derek H R Barton
