Frequency and intensity analyses of the far infrared ν5 band system of cyanogen (C2N2) and applications to Titan

► First global analysis of cyanogen on new high resolution study in the far infrared. ► New determination of band intensities including 15N isotopologue. ► New determination of vibrational transition moment and very good agreement with band intensities. ► Applications to the search of cyanogen isotopologues on Titan.
