## Abstract Acylation of allyl alcohols induces strong carbon shifts, shielding γ and deshielding δ effects. These shifts are a consequence of through‐bond polarization of the olefinic carbons. Allyl ethers show similar, but milder perturbations. The olefinic carbon shifts reveal a strong concentra

Abstract
Carbon‐13 chemical shifts for N‐benzylidenebenzylamines are affected by substituents up to eleven bonds away from the substituent group. The data correlate well with Hammett constants.

## Abstract Carbon‐13 NMR chemical shifts have been measured in a number of binary mixtures of normal alkanes. Intrinsic solvent shifts are deduced from the shifts and the relevance of some small substituent effects in alkanes is discussed. A comparison is made between solvent effects and thermally
## 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
