The ν 1, ν 2, and ν 3 Band Systems of 3-Isocyano-2-propynenitrile (NCCCNC): Comparison with the ν 4 System of Dicyanoacetylene

The hot bands in the ν 1, ν 2, and ν 3 band systems of NC–CC–NC (3-isocyano-2-propynenitrile) have been investigated and transitions from n v 9-levels with n up to 4 have been identified. Two weak bands have also been observed in the gas phase infrared spectrum at 2157 and 2410 cm −1, of which the l...

Summary:The hot bands in the ν 1, ν 2, and ν 3 band systems of NC–CC–NC (3-isocyano-2-propynenitrile) have been investigated and transitions from n v 9-levels with n up to 4 have been identified. Two weak bands have also been observed in the gas phase infrared spectrum at 2157 and 2410 cm −1, of which the latter is probably 2 v 4. A preliminary investigation of some analogous hot bands in the v 4 band system of the related molecule NC–CC–CN (dicyanoacetylene) is also reported.
