## 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

✦ Synopsis
The question of the relative importance of through-bond and through-space interactions in determining 13C nmr chemical shifts, as well as the relative importance of electric field effects and induced magnetic fields are still not answered. We have examined the 13C nmr spectra of a number of sets (F,Cl,Br,I) of bicyclic halides as well as other aliphatic and alicyclic halides. Some

There are many literature examples correlating C-13 n.m.r. substituent chemical shifts in substituted benzenes with Bsamett substituent constants.' The direction of these substituent chemical shifts has been logically explained in terms of substituent electronic properties; the electron donors resul
## Abstract __N__,__N__‐diisopropylamides and ‐thioamides show hindered rotation around the NCH bonds, and the presence of mixtures of conformational isomers can be demonstrated at temperatures below 273 K in solution. ^1^H and ^13^C NMR spectra of these conformers are measured and assigned. The ^
## 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 The ^13^C NMR chemical shifts of the α, β, γ and δ carbons of aliphatic fluorides, chlorides, bromides and iodides can be reproduced by a four‐parameter equation; the charge __Q__ on the carbon atom, the number of hydrogen atoms three bonds away, __N__~3H~, the interactions of the polar
## 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
