✦ Synopsis

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 2v 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.
