✦ Synopsis

Although the subject of numerous investigations, the origins of 13C nmr chemical shifts are still not well understood.a In order to simplify the problem, we have examined a wide variety of halogen substituted (F,Cl,Br,I) compounds. The similarity of the C-X bond dipoles" should minimize contributions from field effect at reasonable distance from the site
