Abstract
Complete analyses of the nuclear magnetic
resonance spectra of 5-(but-3-en-1-yny1)-2,2'-bithienyl (I) and α-terthienyl
(II) were carried out. The chemical shifts and coupling constants obtained for
the ABC systems present are compared with those determined by the approximation
method of Hoffman and Gronowitz. This method affords remarkably good chemical
shift values for even very strongly coupled systems.
