Abstract
Infrared spectra of crystalline HC3N and C2H2 were investigated at several temperatures between 15 and 150 K. The characteristics of the 505 and 753 cm−1 bands of HC3N are in complete agreement with the emission spectral data on Titan obtained by the Voyager IRIS instrument, thus confirming the identification of crystalline HC3N on Titan. A composite spectrum in the 720-800 cm−1 region, with contributions from HC3N and C2H2 in crystalline phases, reproduces the Voyager emission data in that region, thus providing a suggestion for the identification of crystalline C2H2 on Titan.
