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 t

✦ Synopsis
The millimeter-wave spectrum of HCCCCF was observed in the ground state as well as in the low-lying vibrationally excited states nu7, nu8, nu9 and also associated nu8 + nu9, 2nu9, and 3nu9 states. The HCCCCF molecule was produced by a dc glow discharge in a flowing vapor of 2,3,4,5,6-pentafluorostyrene. The l-type doubling constants determined are in good agreement with the values predicted from the harmonic force field calculation. Copyright 1999 Academic Press.

Almost 300 new rotational transitions within the fundamental vibrational level v 10 = 1 of propyne have been measured in selected regions between 495 and 925 GHz spanning the quantum numbers 28 ≤ J ≤ 54 and 0 ≤ K ≤ 16. The accuracies are mostly between 10 and 20 kHz. In addition, the J = 4 and 5 tra
