Nuclear Magnetic Resonance. A definitive review of interproton allylic spin-spin coupling has been made which contains much of relevance to alicyclic systems. Study of the n.m.r. spectra of 36 axially and equatorially substituted cyclo-hexanols has identified some unexpected chemical shift effects. Substituent-dependent additive shielding increments were used successfully to calculate the chemical shift of methine H atoms present, so confirming the observation of some axial H atom shifts at lower fields than the equatorial H atom resonances, i.e. an inversion of the accepted behaviour. 

An ester is a compound whose structure may be derived by the replacement of the replaceable hydrogen of an acid by an alkyl, aryl, alicyclic or heterocyclic group. The most important esters are these derived from carboxylic acids the structural formula of these esters is R-CO—O—R For the purposes of this chapter, polyesters are defined as polymers containing recurring —CO—0— groups in the main chain. It may be noted that this definition excludes polymers of esters such as vinyl acetate and methyl methacrylate since in these polymers the ester groups occur in side-chains and not in the main chain. 

Cooper [40] studied the TLC behavior of four trans-cis pairs of some geometric isomers, intermediates in the synthesis of some alicyclic analogues of mescaline on silica gel with different mobile phases without founding a definite correlation. Generally, the cii-isomers migrated faster than the trun -isomers.
