## Abstract ^13^C NMR spectra of thiols, sulfinic acids, sulfinyl chlorides, sulfonic acids and sulfonic anhydrides have been obtained. The data are discussed in terms of the additivity of the deshielding effects exerted by the sulfur functionality at the Ξ±β or Ξ²βposition, and the shielding effects

The 13C NMR chemical shifts of nitriles and nitro compounds derived from nineteen aliphatic and seven aromatic systems have been recorded and assigned. The shifts are compared with those of the hydrocarbons to give the substituent effects of the CN and NO2 groups.
## Abstract Selected model carboxylic acids and esters dissolved in deuteriochloroform have been studied by carbonβ13 nuclear magnetic resonance under standardized conditions. Assignments of the chemical shifts have been made for all samples, and the spinβlattice relaxation times and nuclear Overha
