Abstract
The IR spectrum of gaseous dicyanoacetylene, NC-C equivalent to C-CN, is studied in the 3500-220 cm(-1) range, employing Fourier transform s pectroscopy. A total of 17 bands are analyzed and assigned. The absolu te intensity is determined and the associated uncertainty is estimated for each of the bands. The resulting data are used to study the detec tability of gaseous C4N2 in Titan's atmosphere. In particular a better estimate of the upper limits of its abundance in Titan's atmosphere i s obtained when our results are used to reanalyse Voyager IRIS infrare d spectra.
