C chemical shifts for a series of substituted nitronaphthalenes have been obtained by several assignment techniques. Deviations from additivity are mainly observed in the ortho-disubstituted compounds and are due, in part, to the variations of the anisotropic terms for the substituents studied. 13

Examination of the pKMCS(80% methylcellosolve) of amino alcohols and amines derived from tert-butylcyclohexane shows that introduction of a tertiary butyl group in the adjacent position to a hydroxyl leads, by comparison to the non-substituted cyclohexanol, to a flattening of this portion of the ring when the hydroxyl and tert-butyl groups are trans; when the groups are cis a straightening occurs.
