Comments: The absolute photoabsorption cross section of propyne was recorded between 62000 and 88000 cm-1 by using the vacuum-ultraviolet, 
Fourier-transform spectrometer. Room-temperature spectra were recorded in a flowing cell at 0.9 cm-1 resolution, and jet-cooled spectra were recorded 
at 1.8 cm-1 resolution.
