The 1H and 13C NMR spectra of 4-substituted phenylthiol acetates, benzoates and cinnamates and the 17O NMR spectra of a few thiol acetates were measured. The 13C chemical shifts of C-1 of the thiol esters when correlated with appropriate substituent-induced chemical shifts (SCS) of monosubstituted b

Ab initio IGLO (individual gauge for localized molecular orbital) methods of SCF-MO theory were used to extend studies of the conformational dependences of isotropic 13C NMR chemical shifts to n-hexane and three 1-substituted pentanes (X \ CN, OH, F).

17O, 13C and 1H NMR spectra for paraand meta-substituted 4-arylaminopent-3-en-2-ones (acyclic enaminones, 1 and 2) and 3-arylaminocyclohex-2-en-1-ones (cyclic enaminones, 3 and 4) are reported. The 17O, 13C and 1H shift values of these enaminones correlate well with and constants in the correlations
