## Abstract A study has been made of the ^13^C chemical shifts of a number of acyclic alkanes, alkenes, nitriles and ketones which contain quaternary carbon atoms. Similar data have also been obtained for the series of compounds involved in the synthesis of triisopropylacetic acid. Substituent effe

## Abstract The ^13^C NMR spectra of several monocyclic Ξ³βsultones(1,2βoxathiolane 2,2βdioxides) and Ξ΄βsultones(1,2βoxathiane 2,2βdioxides) have been determined and are presented herein. The chemical shifts of the ring carbons of these compounds are compared in terms of conformational, electronic a
## Abstract ^13^C NMR Substituent chemical shift (SCS) increments have been determined for the carbonyl carbon of a variety of substituted benzaldehydes and acetophenones. The ^13^C NMR chemical shift of the carbonyl carbon can be predicted for many diβ and trisubstituted benzaldehydes and acetophe
