Literature and unpublished data o n phenols have been analysed to give phenol substituent effects for acyclic alkanes. The results are analysed in terms of the a-branching of the alkyl phenol side chain.
## Abstract ^13^C chemical shifts and ^31^P,^13^C coupling constants are reported for nine 1‐hydroxyalkylphosphonic and two additional phosphonic acids. The α‐substituent‐induced chemical shifts (α‐SCS) of the phosphonate group were calculated and their non‐additivity was observed. Good linear corr
## Abstract ^13^C NMR chemical shifts of 22 __ortho__‐substituted nitrobenzenes are reported. Except for those on C‐3 and C‐5, the effects of the interacting nitro group and the substituent are non‐additive. The chemical shifts of the __ipso__, __ortho__ and __para__ carbons in the spectra and thos
