Vibrational Predissociation Spectra of C₂ N^- and C₃ N^- : Bending and Stretching Vibrations.

ABSTRACT: We present infrared predissociation spectra of C₂ N^- (H₂ ) and C ₃ N^- (H₂ ) in the 300-1850 cm^-1 range. Measurements were performed using the FELion cryogenic ion trap end user station at the Free Electron Lasers for Infrared eXperiments (FELIX) laboratory. For C₂ N^- (H₂ ), we detected the CCN bending and CC-N stretching vibrations. For the C₃ N^- (H₂ ) system, we detected the CCN bending, the CC-CN stretching, and multiple overtones and/or combination bands. The assignment and interpretation of the presented experimental spectra is validated by calculations of anharmonic spectra within the vibrational configuration interaction (VCI) approach, based
