Abstract
Carbon‐13 n.m.r. spectra of formic, acetic, propionic and butyric acid amides with N,N‐di‐n‐alkyl substituents have been completely assigned with the aid of extensive double resonance experiments. The data obtained were used to study long range steric effects on chemical and solvent shifts.

## Abstract ^13^C n.m.r. chemical shifts and carbon‐proton coupling constants of 2‐substituted pyrimidines are reported. The carbon chemical shifts are correlated with π‐electron densities. Substituents which cause deshielding at the directly bound carbon (e.g. NH~2~, OCH~3~ and F) exert a more pow
## Abstract The noise‐decoupled and gated‐decoupled ^13^C n.m.r. spectra of quercetin and rutin are studied and assignments are proposed. The previous assignments of carbons 2 and 4′, carbons 5 and 9, carbons 6 and 8 have been reversed.
## Abstract The conformations of dihydrolysergamides and 10‐methoxydihydrolysergamides have been inferred from the study of the chemical shifts of the amide hydrogens and their temperature dependence. The ^13^C chemical shifts have been shown to be sensitive to conformational changes of the piperid
## Abstract Correction of measured chemical shifts by subtracting the diamagnetic contributions caused by certain substituents on various carbons of a molecule leads to data that allow a reasonable interpretation of substituent effects on chemical shifts in ^13^C n.m.r. spectroscopy. It is shown th
