✦ Synopsis
Fourier transform emission spectra from flowing CO2 excited by active nitrogen have been recorded in the 4.5 urn region, with a resolution of 0.0054 cm-', for different time intervals between the mixing of the two gases and observation of the emission. Significant frequency shifts (reaching 30 times the absolute uncertainty of the experimental frequencies) and linewidth changes are observed depending on the time interval and the value of the quantum number q for thousands of rovibrational lines belonging to u, vi u, +v, I&( y -1) vibrational transitions.
