Abstract
The IR spectrum of ethanenitrile (acetonitrile), a compound recently d etected, in the atmosphere of Titan by millimetre observation, is stud ied in the 3500-250 cm(-1) region. The most intense vibration bands ar e characterized and, for each band, the absolute intensity is determin ed with its uncertainty. Then, the data obtained are used to study the detectability by infrared spectroscopy of this compound in Titan's at mosphere. Especially, the upper limit of its stratospheric abundance i s estimated with the help of the already available infrared spectra of Titan.
