    Submillimeter-wave Spectroscopy of HCN in Excited Vibrational States.

  • Original language description

    Measurements of the rotational spectrum of HCN in excited vibrational states have been extended to higher J values. The transitions reach J = 8 üř 7 around 710 GHz for most vibrational states studied in this investigation and J = 22 üř 21 near 2 THz forthe (020) vibrational state. Using a pure sample of gaseous HCN at íŔ350 K, selected states up to one quantum in the C-H stretching vibration at 3311.5 cm-1 have been investigated. Even transitions having two quanta in the C-H stretch could be studied employing a glow discharge in a gas mixture of CH4 and N2. Molecular constants in 13 vibrational states have been obtained, several of which have been studied for the first time by rotational spectroscopy. The vibrational temperature in the discharge system is found to be about 1500 K for the stretching vibrational modes and about 600 K for the bending states.
