The 13C NMR spectra of thirty-seven alkynoic acids (C8-C18) and ten alkadiynoic acids (C18 and C20) are reported and interpreted. The influence of COOH, COOCH3, CH3, and C identical to C groups on the chemical shifts of nearby carbon atoms is assessed. These influences are largely additive so that available spectra are readily interpreted and the spectra of new compounds of this type can be predicted. These preliminary results indicate that 13C NMR spectroscopy should be of considerable value in the structural identification of acetylenic compounds. |
