✦ Synopsis

The infrared spectrum of (\mathrm{C}{4} \mathrm{H}{2}), butadyine (also called diacetylene), has been experimentally investigated in the region from 250 to (4300 \mathrm{~cm}^{-1}) using a Fourier transform spectrometer. A total of 12 bands have been analyzed. For each band, the characteristic wavenumber has been deduced and the values of the absolute band intensities have been systematically determined together with their associated uncertainties. The results provide important data for planetary studies. In particular, a better estimate of the mean stratospheric abundance of butadiyne in Titan's atmosphere is obtained: its value is about (50 %) higher than previously reported. 1995 Academic Press.
