15-MU-M EMISSION FT SPECTRA OF (CO2)-C-12-O-16 EXCITED TO HIGH VIBRATIONAL LEVELS - TRANSITIONS UPSILON-1'UPSILON-2'L'UPSILON-3-]-UPSILON-1-UPSILON-2L-UPSILON-3 (UPSILON-3 = 1, 2, 3)

Emission spectra of CO2, vibrationally excited by a DC electric discharge, were recorded at a resolution of 0.006 cm-1, using a Fourier transform spectrometer (Bruker 120HR), in the spectral range of 13-18 μm. Results concerning 30 vibrational transitions with v3 = 1, 2, 3 of 12C16O2 are reported. The band centers and the spectroscopic constants for all the vibrational levels involved are given. They reproduce the experimental wavenumbers with a rms of the order of 6 × 10-4 cm-1 for transitions with v3 = 1 and of 5 × 10-3 cm-1 for the others. © 1993 Academic Press Inc.
