✦ Synopsis

The 'H spectra with natural abundance -C satellites of propyne partially oriented in the liquid crystals ZLI 1167 and Merck Phase IV were analysed and molecular structures determined from the direct couplings corrected for harmonic vibrations. The resulting internuclear distance ratios and angles agree with microwave data and the solvent effects are small, i.e. of the order of 1% and 0.5" in the methyl p u p , and 2% in the acetylenic moiety.
