The chromatography of a series of phenylated p-cresols has been studied. It provides evidence that carbon-carbon hyperconjugation is of importance in determining the RM values of these compounds.

The constitutive effects of intramolecular hydrogen bonding on the chromatography of aromatic o-hydroxy-aldehydes and o-hydroxy-esters have been studied. It is shown that the degree of hydrogen bonding between the two ortho-groups as indicated by the shifts Δν(CO) in the infra-red spectra of the compounds can be quantitatively correlated with the values of ΔRM(CHO) or ΔRM(COOCH3) found by comparing the RM values of the compounds with those of the parent phenols. Both the chromatographic and infra-red effects can be related to the bond order of the double bond (in the parent hydrocarbon) bearing the two chelating groups. Intramolecular hydrogen bonding is an important factor affecting the precise theoretical calculation of RM. This study provides an example of how such a constitutive effect can be evaluated.

A series of o-nitroso derivatives of phenols, alkoxyphenols, coumaranols and chromanols have been chromatographed. Two reversed phase and one direct phase system have been used. The correlation of the RM values of these compounds with their structure is at present impossible, being complicated by the combined occurrence of tautomerism and internal hydrogen bonding. Since these factors are interdependent and since they also depend on the nature of the solvents, the chromatography of o-nitrosophenols cannot be satisfactorily interpreted in terms of the electronic structure of the parent phenols or the relevant bond orders in the parent hydrocarbons.
