Abstract
The symmetry of the rotation-vibration spectra for linear triatomic molecules is described by means of the group U(5).The rotation-vibration levels of linear triatomic molecules NCN and COS are calculated.The infrared absorption line intensities are calculated for the molecule COS.The results are in good agreement with the experimental values.
