## Abstract ^13^C n.m.r. chemical shifts and carbonโproton coupling constants of 2โsubstituted pyrimidines are reported. The carbon chemical shifts are correlated with ฯโelectron densities. Substituents which cause deshielding at the directly bound carbon (e.g. NH~2~, OCH~3~ and F) exert a more pow

## Abstract Carbonโ13 n.m.r. spectra of formic, acetic, propionic and butyric acid amides with __N__,__N__โdiโ__n__โalkyl 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
## Abstract ^13^C n.m.r. chemical shifts and one bond ^13^C, ^1^H coupling constants for cyclopropene and its 1โ and 3โmethyl derivatives as well as for methyl cyclopropane have been measured. The data for cyclopropene are 108ยท9 ppm and 228ยท2 Hz, 2ยท3 ppm and 167ยท0 Hz in the olefinic and allylic pos
