## 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
The ^13^C NMR chemical shifts of the C‐1′ carbon atom of fifteen para‐substituted benzophenones correlate with the ℱ and ℛ substituent constants in a reversed manner.

## Abstract A general equation describing the effect of substituents on α‐carbons in a saturated framework was developed from ^13^C chemical shifts obtained under uniform conditions for selected aliphatic compounds. Experimental correlations for β‐ and γ‐carbons and a discussion of the results are
## Abstract ^13^C chemical shifts obtained under uniform conditions for selected compounds containing secondary aliphatic fragments were employed in a linear regression analysis. Two‐parameter relationships describing the substituent effects in the saturated framework were calculated, and the usefu

## Abstract The ^13^C NMR chemical shifts for 1,3‐dithiolane and 13 methyl substituted derivatives are reported. Substituent effects are derived and compared with those for cyclopentanes and 1,3‐dioxolanes. The magnitude and variety of the substituent effects are best explained with the aid of a ha
