Abstract
A series of substituted phenylacetylenes has been prepared and their infrared spectra recorded. The C≡C and ≡C—H stretching frequencies are only slightly affected by substituents in the phenyl ring. Substituents in the 4-position cause a splitting of the ≡C—H band into two clearly resolved bands of similar intensity, about 10 cm−1apart.Keywords
