## Abstract ^13^C chemical shifts for twentyโnine alkyl and phenyl substituted Nโunsubstituted aziridines have been measured. Additivity parameters for methyl, phenyl and aziridyl carbons have been derived with the aim of testing the consistency of the assignments made on the basis of chemical shif
## Abstract ^13^C NMR chemical shifts of 22 __ortho__โsubstituted nitrobenzenes are reported. Except for those on Cโ3 and Cโ5, the effects of the interacting nitro group and the substituent are nonโadditive. The chemical shifts of the __ipso__, __ortho__ and __para__ carbons in the spectra and thos
## Abstract The ^13^C FTโNMR spectra of thirteen furans, monodiโ or trisubstituted with methyl and/or __t__โbutyl groups, were studied in detail. Substituent effects of methyl and __t__โbutyl groups on the chemical shifts of ring carbon atoms are additive in nonsterically hindered furans. Steric sh
## Abstract The ^13^C chemical shifts of 11 substituted triphenylamines have been determined and the assignment of these resonances made using intensities, ^1^H and ^19^F couplings and predictions from bond additivity relationships. ^13^C chemical shifts at carbons bearing the substituent and at ca
