Infrared emission from highly vibrationally excited NO[sub 2], prepared by collision induced internal conversion, can be detected with 1 cm[sup [minus]1] spectral and 0.5 [mu]s time resolution over the 800--10 000 cm[sup [minus]1] range by time-resolved Fourier transform emission spectroscopy. The energy distribution of vibrationally excited NO[sub 2] during collisional deactivation can be extracted from the emission spectra and shows that the energy loss per collision increases dramatically from [lt]50 cm[sup [minus]1] below 13 000 cm[sup [minus]1] energy to 1300 cm[sup [minus]1] at 20 000 cm[sup [minus]1] energy.
